# @omniroute/opencode-plugin
> **Recommended way to use OmniRoute with OpenCode.** Pulls a live model catalog from `/v1/models` (including `-low`/`-medium`/`-high`/`-thinking` variants as first-class IDs), aggregates combos via `/api/combos` using a least-common-denominator capability/limit join, sanitizes Gemini tool schemas in flight, and supports multiple side-by-side OmniRoute instances out of the box.
## Why this and not `@omniroute/opencode-provider`?
`@omniroute/opencode-provider` is the legacy config-generator package — it writes a frozen `provider.omniroute` block into `opencode.json` with a **hardcoded list of 8 models** ([`OMNIROUTE_DEFAULT_OPENCODE_MODELS`](https://github.com/diegosouzapw/OmniRoute/blob/main/%40omniroute/opencode-provider/src/index.ts#L48-L56)). It works on the CLI but in the **OpenCode Desktop / Web** builds (Tauri / Electron) the runtime re-runs the model picker and the static block surfaces only a few of those — and they drift behind the live OmniRoute catalog.
This plugin solves that by:
- Fetching `/v1/models` and `/api/combos` **at OpenCode startup, in Node.js** — no CORS, no WebView restrictions
- Emitting the provider block **dynamically** in the plugin's `config`/`provider` hook — so `opencode.json` only needs the plugin entry, not a static `provider.omniroute`
- Re-fetching on a configurable TTL (default 5 min), so new models / combo changes in the OmniRoute UI appear without restarting OpenCode
- Computing `limit.context` for combos as `min(member.context_length)` from the live catalog (no more `null` values that cause 4K-token truncation)
- **Auto-pickup of `interleaved` capability** for thinking models (merged via PR #3138)
**If you only have the legacy `opencode-provider` block in your `opencode.json`, replace it with a single plugin entry.** No other config changes required — the same `auth.json` API key works.
## Install
The plugin ships **pre-built inside the `omniroute` npm package** since v3.8.23.
If you have OmniRoute installed, the plugin is already on disk:
```sh
# 1. One command — copy the plugin into OpenCode and update opencode.json
omniroute setup opencode --auth
# 2. Follow the interactive prompt to enter your OmniRoute API key
# 3. Restart OpenCode — /models lists the full live catalog
```
The `--auth` flag runs `opencode auth login --provider omniroute` automatically.
Use `--base-url` to point at a non-default OmniRoute address:
```sh
omniroute setup opencode --base-url https://or.example.com --auth
```
### What it does
1. Locates the bundled plugin inside the omniroute installation
2. Copies `dist/` + `package.json` to `~/.config/opencode/plugins/omniroute/`
3. Writes/updates `opencode.json` with the plugin entry (idempotent, replaces legacy entries)
4. (With `--auth`) runs `opencode auth login` so the API key is stored
Re-run any time to update the plugin or change the base URL. Older entries for
`@omniroute/opencode-provider` or the legacy `opencode-omniroute-auth` package are
automatically cleaned up.
### Manual install (without omniroute CLI)
If you cannot run `omniroute setup opencode` (local dev, CI, air-gapped), reference
the built artifact directly:
```sh
cd @omniroute/opencode-plugin && npm run build && npm pack
# then extract into ~/.config/opencode/plugins/omniroute-opencode-plugin/
```
And add the entry to `opencode.json` manually (see Quick Start below).
Peer dep: `@opencode-ai/plugin` (managed by your OpenCode install).
## Quick start (single instance, manual)
```jsonc
// opencode.json
{
"$schema": "https://opencode.ai/config.json",
"plugin": [
[
"./plugins/omniroute-opencode-plugin/dist/index.js",
{
"providerId": "omniroute",
"baseURL": "https://or.example.com",
},
],
],
}
```
```sh
opencode auth login --provider omniroute
# prompts for the OmniRoute API key, writes to ~/.local/share/opencode/auth.json
```
> ⚠ Use the `--provider` flag explicitly. `opencode auth login omniroute` is parsed as a positional `url` argument by current OC releases (≤1.15.5) and fails with `fetch() URL is invalid`. Tracked upstream.
Restart OpenCode. `/models` lists the full live catalog. Variants (`-low`, `-medium`, `-high`, `-thinking`) and combos appear as first-class IDs — OmniRoute is the source of truth, no client-side synthesis.
## Multi-instance (prod + preprod side-by-side)
> ⚠ OC ≤1.15.5 dedupes plugin loads by absolute module path. Two `plugin:` entries pointing at the same `dist/index.js` collapse into one (last-listed options win). Workaround: install the plugin twice into separate directories so each entry resolves to a distinct module file. v0.2.x will introduce an `instances: [...]` shape that registers N providers from a single load.
### Dual-install workaround (works today on OC ≤1.15.5)
Pack the plugin once, extract it twice into named directories, then point each `plugin:` entry at its own copy:
```sh
# 1. Build + pack the plugin (run from the plugin worktree)
cd /path/to/OmniRoute/@omniroute/opencode-plugin
npm run build
npm pack
# produces omniroute-opencode-plugin-0.1.0.tgz
# 2. Extract one copy per OmniRoute endpoint
mkdir -p ~/.config/opencode/plugins/omniroute-opencode-plugin-prod
mkdir -p ~/.config/opencode/plugins/omniroute-opencode-plugin-preprod
tar -xzf omniroute-opencode-plugin-0.1.0.tgz -C ~/.config/opencode/plugins/omniroute-opencode-plugin-prod --strip-components=1
tar -xzf omniroute-opencode-plugin-0.1.0.tgz -C ~/.config/opencode/plugins/omniroute-opencode-plugin-preprod --strip-components=1
```
Then in `~/.config/opencode/opencode.json` reference each directory by absolute path:
```jsonc
{
"$schema": "https://opencode.ai/config.json",
"plugin": [
[
"./plugins/omniroute-opencode-plugin-prod/dist/index.js",
{
"providerId": "omniroute",
"displayName": "OmniRoute",
"baseURL": "https://or.example.com",
},
],
[
"./plugins/omniroute-opencode-plugin-preprod/dist/index.js",
{
"providerId": "omniroute-preprod",
"displayName": "OmniRoute Preprod",
"baseURL": "https://or-preprod.example.com",
},
],
],
}
```
Paths are relative to `~/.config/opencode/`. Each entry now resolves to a distinct module file, so OC loads them as two separate plugin instances. Authenticate each:
```sh
opencode auth login --provider omniroute
opencode auth login --provider omniroute-preprod
```
Each entry gets its own provider id, its own model picker entry, its own slot in `auth.json`, and its own TTL cache. Closures are isolated per plugin instance — no cross-talk.
### After publish (`@omniroute/opencode-plugin` npm)
Once the package is published, the dual-install becomes two `npm install --prefix` commands instead of `tar -xzf`:
```sh
mkdir -p ~/.config/opencode/plugins/omniroute-opencode-plugin-prod
mkdir -p ~/.config/opencode/plugins/omniroute-opencode-plugin-preprod
npm install --prefix ~/.config/opencode/plugins/omniroute-opencode-plugin-prod @omniroute/opencode-plugin
npm install --prefix ~/.config/opencode/plugins/omniroute-opencode-plugin-preprod @omniroute/opencode-plugin
```
`opencode.json` paths become `./plugins/omniroute-opencode-plugin-prod/node_modules/@omniroute/opencode-plugin/dist/index.js` (and the preprod equivalent).
## Features
| Feature | What it does | Hook |
| ------------------------------------------- | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | ---------------------------- |
| Dynamic `/v1/models` | Pulls live catalog (455+ entries on prod) on each refresh, TTL-cached | `provider.models` |
| Variants pass-through | `-low`/`-medium`/`-high`/`-thinking` ship as first-class IDs from OmniRoute (no client synthesis) | `provider.models` |
| Combo LCD aggregation | Combos appear with intersected capabilities + min context/output across members | `provider.models` + `config` |
| `combo/<slug>` namespace + `Combo: ` prefix | Combos surface under `combo/claude-primary` (not the upstream UUID) and the picker shows `Combo: claude-primary` so they stand apart from raw provider/model pairs | both hooks |
| Nice names + cost | `/api/pricing/models` display names AND `/api/pricing` per-million-token cost overlaid onto the live catalog | both hooks |
| Canonical-twin dedup + alias-fallback | `/v1/models` exposes the same upstream model under both short alias (`cc/claude-opus-4-7`) and canonical name (`claude/claude-opus-4-7`); the plugin drops the canonical twin when an alias twin exists (no duplicate rows in the picker) and reverse-maps canonical → alias to pick up enrichment for short aliases (`dg/nova-3 → Deepgram - Nova 3`) that `/api/pricing/models` only indexes by canonical | both hooks |
| Compression pipeline tags | Combo names get tagged with their compression pipeline (e.g. `Combo: claude-primary [rtk🟡 → caveman🟠]`) when `features.compressionMetadata: true`. Intensity tokens render as a traffic-light emoji: 🟢 lite/minimal · 🟡 standard · 🟠 aggressive/full · 🔴 ultra | both hooks |
| Provider-tag prefix | Prepend short upstream-provider label to enriched names (e.g. `Claude - Claude Opus 4.7` vs `Kiro - Claude Opus 4.7`, `GHM - GPT 5`) so same-id models routed via different upstream connections group visibly in the picker (default-on, opt-out via `features.providerTag: false`) | both hooks |
| Usable-only filter | Filter to providers with at least one healthy connection in `/api/providers` (opt-in via `features.usableOnly`) | both hooks |
| Disk-cache fallback | Last-known-good catalog persisted to disk; hydrates on a cold start when `/v1/models` is unreachable (default-on, opt-out via `features.diskCache: false`) | `config` |
| Bearer injection + suffix-spoof guard | Adds `Authorization` on baseURL-matched requests only | `auth.loader.fetch` |
| Gemini schema sanitization | Strips `$schema`/`$ref`/`additionalProperties` for `gemini-*`/`google-vertex-gemini/*` | `auth.loader.fetch` wrap |
| Multi-instance | Each plugin entry binds to its own `providerId`; closures isolated | factory |
| Config-hook shim | OC ≤1.15.5 fallback: writes static catalog into `config.provider[id]` (config hook is the only one that fires in `serve` mode on these versions) | `config` |
## Plugin options
| Option | Type | Default | Description |
| --------------- | -------- | ------------------------------------------ | ---------------------------------------------------------- |
| `providerId` | `string` | `"omniroute"` | OpenCode provider id; must be unique across plugin entries |
| `displayName` | `string` | `"OmniRoute"` or `OmniRoute (<id>)` | Label in the OC UI |
| `modelCacheTtl` | `number` | `300000` (5 min) | `/v1/models` TTL in ms |
| `baseURL` | `string` | resolved from `auth.json` after `/connect` | Override OmniRoute base URL |
| `features` | `object` | see below | Feature toggles (all opt-in/out, defaults preserve v0.1.0) |
### `features` block
Every field is optional. Defaults mirror v0.1.0 behaviour so existing `opencode.json` files do not need to change.
| Feature | Type | Default | What it does |
| --------------------- | --------- | ------- | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- |
| `combos` | `boolean` | `true` | Discover `/api/combos` and surface them as pseudo-models with LCD capabilities. Combos are keyed under the `combo/<slug>` namespace and labelled `Combo: <name>` in the model picker so they're distinguishable from raw provider/model pairs. |
| `enrichment` | `boolean` | `true` | Pull display names from `/api/pricing/models` AND per-million-token pricing (`input`, `output`, `cached``cacheRead`, `cache_creation``cacheWrite`) from `/api/pricing`, then overlay both onto the live catalog (so the UI shows `Claude 4.7 Opus` with `cost.input: 5`, `cost.output: 25` instead of raw IDs and zeroed cost). |
| `compressionMetadata` | `boolean` | `false` | Pull `/api/context/combos` so combo names get tagged with their compression pipeline, e.g. `Combo: claude-primary [rtk🟡 → caveman🟠]`. Intensity tokens render as traffic-light emoji (🟢 lite/minimal · 🟡 standard · 🟠 aggressive/full · 🔴 ultra) so the picker advertises "how compressed" each combo is at a glance. |
| `providerTag` | `boolean` | `true` | Prepend a short upstream-provider label to the enriched display name with `" - "` separator, so `cc/claude-opus-4-7 → Claude - Claude Opus 4.7` differs visibly from `kr/claude-opus-4-7 → Kiro - Claude Opus 4.7` in the OC TUI model picker. Label resolution: use `/api/pricing/models[<alias>].name` verbatim when ≤8 chars (e.g. `Claude`, `Kiro`, `Codex`, `Qwen`), otherwise fall back to `UPPER(alias)` (e.g. `GitHub Models``GHM`, `Gemini``GEMINI`). Idempotent. Combos intentionally skipped (the `Combo: ` prefix already conveys multi-upstream). |
| `usableOnly` | `boolean` | `false` | Read `/api/providers` and filter the catalog to providers that have at least one connection with `isActive: true` AND `testStatus: 'active'`. Subtract-filter semantics: providers unknown to BOTH the pricing-models catalog AND the connection table pass through (so synthetic prefixes like `agentrouter/*` survive). On fetch failure the filter is disabled for the refresh — never hides the whole catalog. |
| `diskCache` | `boolean` | `true` | Persist the last successful `/v1/models` + `/api/combos` + enrichment + connections + compression snapshot to `${OPENCODE_DATA_DIR ?? ~/.local/share/opencode}/plugins/omniroute-<providerId>.json`. On a subsequent cold start where `/v1/models` throws (network down / IP whitelist drop / 5xx) the static block hydrates from the snapshot so OC's model picker survives offline. Soft-fail on read/write — never blocks publishing. |
| `geminiSanitization` | `boolean` | `true` | Strip `$schema`/`$ref`/`additionalProperties` from tool params when the model id matches `gemini` |
| `mcpAutoEmit` | `boolean` | `false` | Auto-write an `mcp.<providerId>` remote entry into the OC config pointing at `<baseURL>/api/mcp/stream` with the resolved Bearer token |
| `mcpToken` | `string` | _unset_ | Optional separate Bearer for the auto-emitted MCP entry. Falls back to the provider's `apiKey` (from `auth.json`) when unset |
| `fetchInterceptor` | `boolean` | `true` | Inject `Authorization: Bearer` + default `Content-Type` on every outbound request targeting `baseURL` (suffix-spoof guarded) |
#### Example — enrichment + compression tags + MCP auto-emit
```jsonc
{
"plugin": [
[
"@omniroute/opencode-plugin",
{
"providerId": "omniroute",
"baseURL": "https://or.example.com",
"features": {
"combos": true,
"enrichment": true,
"compressionMetadata": true,
"mcpAutoEmit": true,
},
},
],
],
}
```
With `mcpAutoEmit: true`, the plugin synthesises an `mcp.omniroute` entry equivalent to a manual:
```jsonc
"mcp": {
"omniroute": {
"type": "remote",
"url": "https://or.example.com/api/mcp/stream",
"enabled": true,
"headers": { "Authorization": "Bearer <apiKey-from-auth.json>" }
}
}
```
If you want a narrower-scoped Bearer for MCP (different from the chat/inference key), set `features.mcpToken`. Operator overrides win: if you already set `mcp.omniroute` in `opencode.json`, the plugin will not overwrite it.
#### Example — production-leaning defaults (clean picker, offline resilience)
```jsonc
{
"plugin": [
[
"@omniroute/opencode-plugin",
{
"providerId": "omniroute",
"baseURL": "https://or.example.com",
"features": {
"combos": true,
"enrichment": true,
"compressionMetadata": true,
"usableOnly": true,
"diskCache": true,
},
},
],
],
}
```
- `usableOnly: true` drops models whose canonical provider has no healthy connection in your OmniRoute instance — your `/models` picker stays focused on what you can actually call.
- `diskCache: true` (default) writes a snapshot to `${OPENCODE_DATA_DIR}/plugins/omniroute-<providerId>.json` on every healthy refresh. On a cold start where `/v1/models` is unreachable (laptop offline, IP whitelist drop), the snapshot hydrates the static block so OC still shows the catalog instead of a stub.
- `compressionMetadata: true` annotates combo display names with their pipeline using traffic-light emoji for intensity (e.g. `Combo: claude-primary [rtk🟡 → caveman🟠]`) so the picker advertises which compression each combo applies and how heavy it is at a glance. Palette: 🟢 lite/minimal · 🟡 standard · 🟠 aggressive/full · 🔴 ultra. Unknown intensities fall through to raw text (`[rtk:custom-thing]`) so the plugin never hides a value OmniRoute knows but the plugin doesn't.
- `providerTag: true` (default) prepends a short upstream-provider label so the picker shows `Claude - Claude Opus 4.7` for `cc/claude-opus-4-7`, `Kiro - Claude Opus 4.7` for `kr/claude-opus-4-7`, and `GHM - GPT 5` for `ghm/gpt-5` (slot.name `GitHub Models` > 8 chars → abbreviated). Critical when the same model id is sold through multiple upstream connections with different cost/auth/rate-limit profiles. Set to `false` to keep the pre-v3.8.3 unsuffixed format.
## Comparison vs `@omniroute/opencode-provider`
[`@omniroute/opencode-provider`](https://github.com/diegosouzapw/OmniRoute/tree/main/%40omniroute/opencode-provider) is the existing config-generator package — it writes a frozen `provider.<id>` block into `opencode.json` at build time. This plugin is the runtime integration.
| | `@omniroute/opencode-plugin` (this) | `@omniroute/opencode-provider` |
| ----------------- | ----------------------------------- | --------------------------------- |
| Type | OC plugin | Config generator (CLI/build-time) |
| Models | Live from `/v1/models` | Frozen at scaffold |
| Combos | LCD-aggregated live | None |
| Gemini sanitize | Yes | N/A |
| OC UI integration | `/connect`, `/models` | None |
| Multi-instance | Native | Manual |
Both can coexist; pick the one that fits your environment.
## Requirements
- Node `>=22.22.3` (per `engines.node`); tested on Node 22 and 24.
- OpenCode: verified end-to-end against `opencode@1.15.5` with `@opencode-ai/plugin@1.15.6`.
- OC plugin peer (`@opencode-ai/plugin`) `>=1.14.49` for the full feature set (provider hook surfaces models in `/models`). On `<=1.14.48`, the plugin falls back to its `config` hook, writing a static catalog snapshot into `config.provider[id]` so models still appear.
- The plugin uses the OC v1 plugin shape (`default: { id, server }`) — older OC releases that only walk named exports will reject it. Stay on OC ≥1.15.

/**
* Tests for the 3 mrmm-fork features backported to @omniroute/opencode-plugin:
*
* 1. `normaliseFreeLabel` — free-tier model display names get a consistent
* `[Free] ` prefix instead of trailing "(Free)" or ad-hoc "free" words.
*
* 2. `resolveApiBlock` — per-provider-prefix API format routing. Anthropic
* prefixes (`cc/`, `claude/`, `anthropic/`, `kiro/`, `kr/`) get the
* Anthropic SDK block; everything else gets OpenAI-compat.
*
* 3. `debugLog` — JSONL request/response capture, gated by
* `features.debugLog` and togglable at runtime via
* `debugLogEnabled/SetEnabled`.

* This is the contract that lets opencode.json declare prod + preprod
* side by side:
*
* "plugin": [
* ["@omniroute/opencode-plugin", {"providerId": "omniroute-prod", "baseURL": "https://or.example/v1"}],
* ["@omniroute/opencode-plugin", {"providerId": "omniroute-preprod", "baseURL": "https://or-preprod.example/v1"}]
* ]
*
* Assertions:
* - Each invocation returns its own hooks object (no identity reuse).
* - Each `auth` hook carries its own `provider` matching opts.providerId.
* - Each `auth.methods` array is its own array (not the same reference).
* - Calling the factory twice with IDENTICAL opts still yields two
* independent objects (no instance reuse / no shared closure cache).
* - Mutating one instance's auth hook does NOT bleed into the other.
* - Each instance's loader closure captures its OWN baseURL — no
* last-write-wins module-scope state.

# @omniroute/opencode-provider
> ## ⚠️ Deprecated — use [`@omniroute/opencode-plugin`](https://www.npmjs.com/package/@omniroute/opencode-plugin) instead
>
> This package writes a **static** `provider.omniroute` block to `opencode.json` from a hardcoded default model list, so it **drifts behind your live OmniRoute catalog** — adding a model in OmniRoute won't show up in OpenCode until you re-run the generator, and OpenCode Desktop/Web only surfaces a subset of the static models.
>
> **`@omniroute/opencode-plugin`** solves this by fetching `GET /v1/models` from your OmniRoute instance at OpenCode startup, so the model list is always live (see [#3419](https://github.com/diegosouzapw/OmniRoute/issues/3419)). It is now the recommended path.
>
> **One-line migration** — replace the static `provider.omniroute` block in `opencode.json` with a single plugin entry:
>
> ```jsonc
> // opencode.json
> {
> "$schema": "https://opencode.ai/config.json",
> "plugin": ["@omniroute/opencode-plugin"]
> }
> ```
>
> This package is **not removed** and still works for static/offline config generation, but it is no longer actively recommended and won't track new models automatically.
Helper for connecting [OpenCode](https://opencode.ai) to a running [OmniRoute](https://github.com/diegosouzapw/OmniRoute) AI gateway.
The package emits a **schema-valid entry** for `opencode.json` (`https://opencode.ai/config.json`) that delegates the actual runtime to [`@ai-sdk/openai-compatible`](https://www.npmjs.com/package/@ai-sdk/openai-compatible). It does not ship any new HTTP client — OmniRoute already exposes an OpenAI-compatible surface, and OpenCode already speaks it through the AI SDK.
> Pre-1.0. The API may still change. See `CHANGELOG` in the OmniRoute repo for breaking notes.
## Installation
```bash
npm install --save-dev @omniroute/opencode-provider
# or
pnpm add -D @omniroute/opencode-provider
```
You also need OpenCode's own runtime dep, but that's a transitive concern — OpenCode itself ships with `@ai-sdk/openai-compatible`. This package only **generates configuration**.
## Quick start
### 1. Scaffold a fresh `opencode.json`
```ts
import { writeFileSync } from "node:fs";
import { buildOmniRouteOpenCodeConfig } from "@omniroute/opencode-provider";
const config = buildOmniRouteOpenCodeConfig({
baseURL: "http://localhost:20128", // or your OmniRoute deployment URL
apiKey: process.env.OMNIROUTE_API_KEY ?? "sk_omniroute",
});
writeFileSync("opencode.json", JSON.stringify(config, null, 2));
```
The resulting `opencode.json`:
```jsonc
{
"$schema": "https://opencode.ai/config.json",
"provider": {
"omniroute": {
"npm": "@ai-sdk/openai-compatible",
"name": "OmniRoute",
"options": {
"baseURL": "http://localhost:20128/v1",
"apiKey": "sk_omniroute",
},
"models": {
"claude-opus-4-5-thinking": { "name": "claude-opus-4-5-thinking" },
"claude-sonnet-4-5-thinking": { "name": "claude-sonnet-4-5-thinking" },
"gemini-3.1-pro-high": { "name": "gemini-3.1-pro-high" },
"gemini-3-flash": { "name": "gemini-3-flash" },
},
},
},
}
```
### 2. Merge into an existing `opencode.json`
```ts
import { createOmniRouteProvider } from "@omniroute/opencode-provider";
const provider = createOmniRouteProvider({
baseURL: "http://localhost:20128",
apiKey: process.env.OMNIROUTE_API_KEY!,
});
// Place `provider` under provider.omniroute in your opencode.json
```
If you already have an `opencode.json` on disk and want a non-destructive merge from the OmniRoute side, use `omniroute config opencode` from the CLI (ships with the main OmniRoute install) — it preserves comments and unrelated keys.
## API
### `createOmniRouteProvider(options): OpenCodeProviderEntry`
Returns the value to place under `provider.omniroute` inside `opencode.json`.
| Option | Type | Required | Description |
| ------------- | ----------------------- | -------- | ------------------------------------------------------------------------------------------------------------ |
| `baseURL` | `string` | Yes | OmniRoute base URL. Accepts `http://host:port` **or** `http://host:port/v1`. Trailing slashes are tolerated. |
| `apiKey` | `string` | Yes | OmniRoute API key. Use `sk_omniroute` for local installs that have `REQUIRE_API_KEY=false`. |
| `displayName` | `string` | No | Custom name shown in the OpenCode UI. Default: `"OmniRoute"`. |
| `models` | `string[]` | No | Override the surfaced model catalog. Default: 4 curated models — see `OMNIROUTE_DEFAULT_OPENCODE_MODELS`. |
| `modelLabels` | `Record<string,string>` | No | Human-readable labels keyed by model id. |
Throws on empty/invalid input — `baseURL` must be a real URL, `apiKey` must be a non-empty string.
### `buildOmniRouteOpenCodeConfig(options): OpenCodeConfigDocument`
Same options as above, but returns a full document with `$schema` and the `provider.omniroute` wrapper, ready to write to `opencode.json`.
### `normalizeBaseURL(input): string`
Exported for completeness. Strips trailing `/`, deduplicates a trailing `/v1`, and re-appends exactly one `/v1`. Throws on empty / non-URL input.
### Constants
- `OMNIROUTE_PROVIDER_KEY``"omniroute"` (the key used under `provider.*`).
- `OMNIROUTE_PROVIDER_NPM``"@ai-sdk/openai-compatible"` (the runtime delegate).
- `OPENCODE_CONFIG_SCHEMA``"https://opencode.ai/config.json"`.
- `OMNIROUTE_DEFAULT_OPENCODE_MODELS` — readonly list of default model ids.
## Custom model catalog
```ts
import { createOmniRouteProvider } from "@omniroute/opencode-provider";
createOmniRouteProvider({
baseURL: "http://localhost:20128",
apiKey: "sk_omniroute",
models: ["auto", "claude-opus-4-8", "gpt-5.5"],
modelLabels: {
auto: "Auto-Combo (recommended)",
"claude-opus-4-8": "Claude Opus 4.8",
"gpt-5.5": "GPT-5.5",
},
});
```
Duplicates and empty strings are dropped automatically, and order is preserved.
## Troubleshooting
- **Requests 404 with `/v1/v1/...`** — you're on an old version (≤1.0.0). Update to `≥0.1.0` of this re-released package. The new build normalises `baseURL` automatically.
- **`401 Invalid API key`** — your OmniRoute instance has `REQUIRE_API_KEY=true` but the key you supplied doesn't exist there. Create one via the dashboard or set `REQUIRE_API_KEY=false` and use `sk_omniroute`.
- **OpenCode complains the provider has no models** — supply an explicit `models` list; the default 4 may be hidden by your provider visibility settings.
## Related

- [OpenCode](https://opencode.ai) — the agentic CLI consumer.
- [`@ai-sdk/openai-compatible`](https://www.npmjs.com/package/@ai-sdk/openai-compatible) — the runtime delegate that actually speaks HTTP.

/**
* OpenCode provider plugin for OmniRoute AI Gateway.
*
* Generates an OpenCode-compatible provider object that points to a running
* OmniRoute instance. The output follows the OpenCode config schema
* (https://opencode.ai/config.json) and delegates the runtime to
* `@ai-sdk/openai-compatible` so OpenCode can drive any OmniRoute-exposed
* model through its standard OpenAI-compatible client.
*
* Two ways to consume the helper:
*
* 1. As code, when you build your own opencode.json programmatically:
*
* ```ts
* import { buildOmniRouteOpenCodeConfig } from "@omniroute/opencode-provider";
* const config = buildOmniRouteOpenCodeConfig({
* baseURL: "http://localhost:20128",
* apiKey: "sk_omniroute",
* });
* // config -> { $schema, provider: { omniroute: { npm, name, options, models } } }
* ```
*
* 2. As a single-provider entry to merge into an existing opencode.json:
*
* ```ts
* import { createOmniRouteProvider } from "@omniroute/opencode-provider";
* const provider = createOmniRouteProvider({ baseURL, apiKey });
* // provider -> the value to place under provider.omniroute in opencode.json
* ```
*
* Note: `baseURL` accepts both `http://host:port` and `http://host:port/v1`.
* The helper normalises trailing slashes / `/v1` so you never get `/v1/v1`.
