title: Model Gateway
|
|
description: Build AI features from Swift with the OpenRouter key provisioned by InsForge
|
|
---
|
|
|
|
## Overview
|
|
|
|
InsForge provisions an OpenRouter API key for Model Gateway projects. New Swift applications should call OpenRouter directly from trusted server-side code, a backend API, or another secure boundary. Do not embed the OpenRouter key in an iOS, macOS, tvOS, or watchOS app binary.
|
|
|
|
The previous InsForge Swift AI SDK methods are deprecated compatibility wrappers. Use the InsForge SDK for database, auth, storage, functions, and realtime; use OpenRouter for model calls.
|
|
|
|
## Recommended Architecture
|
|
|
|
```mermaid
|
|
sequenceDiagram
|
|
participant App as Swift App
|
|
participant API as Your Backend
|
|
participant OR as OpenRouter
|
|
|
|
App->>API: User prompt or app request
|
|
API->>OR: OpenRouter request with server-side key
|
|
OR-->>API: Model response
|
|
API-->>App: App-specific response
|
|
```
|
|
|
|
## Server-Side OpenRouter Call
|
|
|
|
Use the OpenAI SDK or REST from your backend. For TypeScript backends:
|
|
|
|
```typescript
|
|
import OpenAI from 'openai';
|
|
|
|
const openai = new OpenAI({
|
|
baseURL: 'https://openrouter.ai/api/v1',
|
|
apiKey: process.env.OPENROUTER_API_KEY,
|
|
});
|
|
|
|
const completion = await openai.chat.completions.create({
|
|
model: 'openai/gpt-4o-mini',
|
|
messages: [{ role: 'user', content: 'Summarize this note.' }],
|
|
});
|
|
```
|
|
|
|
## Calling Your Backend from Swift
|
|
|
|
```swift
|
|
struct ChatRequest: Encodable {
|
|
let prompt: String
|
|
}
|
|
|
|
struct ChatResponse: Decodable {
|
|
let text: String
|
|
}
|
|
|
|
func sendPrompt(_ prompt: String, sessionToken: String) async throws -> ChatResponse {
|
|
let url = URL(string: "https://your-app.example/api/chat")!
|
|
var request = URLRequest(url: url)
|
|
request.httpMethod = "POST"
|
|
request.setValue("Bearer \(sessionToken)", forHTTPHeaderField: "Authorization")
|
|
request.setValue("application/json", forHTTPHeaderField: "Content-Type")
|
|
request.httpBody = try JSONEncoder().encode(ChatRequest(prompt: prompt))
|
|
|
|
let (data, response) = try await URLSession.shared.data(for: request)
|
|
guard let httpResponse = response as? HTTPURLResponse,
|
|
(200..<300).contains(httpResponse.statusCode) else {
|
|
throw URLError(.badServerResponse)
|
|
}
|
|
|
|
return try JSONDecoder().decode(ChatResponse.self, from: data)
|
|
}
|
|
```
|
|
|
|
Use an app session token or another user-scoped credential for your backend route. Never send the OpenRouter key from a Swift client.
|
|
|
|
## Legacy InsForge AI Methods
|
|
|
|
These Swift SDK methods are deprecated for new AI integrations:
|
|
|
|
- `insforge.ai.chatCompletion(...)`
|
|
- `insforge.ai.generateEmbeddings(...)`
|
|
- `insforge.ai.generateImage(...)`
|
|
- `insforge.ai.listModels()`
|
|
|
|
They target the deprecated InsForge AI proxy. New integrations should use the OpenRouter key from the dashboard and follow OpenRouter's current API docs for model parameters and capabilities.
