# IETF RFC
|
|
|
|
**Mode**: 🌐 Public · **Domain**: `datatracker.ietf.org`
|
|
|
|
Fetch metadata for any IETF RFC by number — title, abstract, publishing working group, authors, std level, page count, publish date, plus links into the RFC Editor and datatracker. Hits the unauthenticated IETF datatracker directly.
|
|
|
|
## Commands
|
|
|
|
| Command | Description |
|
|
|---------|-------------|
|
|
| `opencli rfc rfc <number>` | Single IETF RFC metadata (title, abstract, working group, authors, std level) |
|
|
|
|
## Usage Examples
|
|
|
|
```bash
|
|
# Modern RFCs
|
|
opencli rfc rfc 9000 # QUIC
|
|
opencli rfc rfc 9110 # HTTP semantics
|
|
|
|
# Classic RFCs
|
|
opencli rfc rfc 791 # IP
|
|
opencli rfc rfc 2616 # HTTP/1.1 (now obsoleted by 9110)
|
|
|
|
# Courtesy: "rfcN" prefix accepted
|
|
opencli rfc rfc rfc9000
|
|
```
|
|
|
|
## Output Columns
|
|
|
|
| Command | Columns |
|
|
|---------|---------|
|
|
| `rfc` | `rfc, title, state, stdLevel, group, groupType, pages, published, authors, abstract, rfcEditorUrl, url` |
|
|
|
|
## Options
|
|
|
|
### `rfc`
|
|
|
|
| Option | Description |
|
|
|--------|-------------|
|
|
| `number` (positional) | RFC number (positive integer ≤ 999999). The `rfc` prefix is accepted as a courtesy. |
|
|
|
|
## Notes
|
|
|
|
- **`abstract` is the full IETF abstract** — RFCs don't truncate well, so the adapter never drops content.
|
|
- **`stdLevel`** classifies the document (e.g. `Proposed Standard`, `Internet Standard`, `Best Current Practice`, `Informational`, `Experimental`, `Historic`).
|
|
- **`group`** is the working group / area / IRTF research group that published the RFC; `groupType` distinguishes (e.g. `WG`, `IETF`).
|
|
- **`rfcEditorUrl`** points at the canonical RFC Editor copy (text/HTML); `url` points at the IETF datatracker page (with rev history, related drafts, and stats).
|
|
- **No API key required.** Datatracker is fast but bursts can return `HTTP 429` → `CommandExecutionError`.
|
|
- **Errors.** Non-numeric input or out-of-range RFC number → `ArgumentError`; unknown RFC → `EmptyResultError`; transport / non-200 → `CommandExecutionError`.
