# YouTube API

YouTube data access via [TranscriptAPI.com](https://transcriptapi.com) — no Google API quota needed.

## Setup

If `$TRANSCRIPT_API_KEY` is not set, read [references/auth-setup.md](references/auth-setup.md) and follow the instructions there to get and store the key.

## Required Headers

Every request needs two headers:

- **Authorization:** `Bearer $TRANSCRIPT_API_KEY`
- **User-Agent:** your agent's name and version if known (e.g. `HermesAgent/0.11.0`, `ClaudeCode/1.0`). Version is optional — agent name alone is fine. Do not omit this header or send a bare default — Cloudflare will return a 403 (error code 1010) and block the request.

## API Reference

Full OpenAPI spec: [transcriptapi.com/openapi.json](https://transcriptapi.com/openapi.json) — consult this for the latest parameters and schemas.

## Endpoint Reference

All endpoints: `https://transcriptapi.com/api/v2/youtube/...`

Channel endpoints accept `channel` — an `@handle`, channel URL, or `UC...` ID. Playlist endpoints accept `playlist` — a playlist URL or ID.

| Endpoint                              | Method | Cost     |
| -------------------------------------- | ------ | -------- |
| `/info?video_url=ID`                   | GET    | **free** |
| `/video/metadata?video_url=ID`         | GET    | 1        |
| `/transcript?video_url=ID`             | GET    | 1        |
| `/search?q=QUERY&type=video`           | GET    | 1        |
| `/channel/resolve?input=@handle`       | GET    | **free** |
| `/channel/info?channel=@handle`        | GET    | 1        |
| `/channel/latest?channel=@handle`      | GET    | **free** |
| `/channel/videos?channel=@handle`      | GET    | 1/page   |
| `/channel/search?channel=@handle&q=Q`  | GET    | 1        |
| `/channel/playlists?channel=@handle`   | GET    | 1/page   |
| `/channel/posts?channel=@handle`       | GET    | 1/page   |
| `/channel/sections?channel=@handle`    | GET    | 1        |
| `/playlist/videos?playlist=PL_ID`      | GET    | 1/page   |

`search` also takes `type=playlist` or `type=movie`, plus first-page-only filters `sort` (`relevance`/`views`), `upload_date`, `duration`, and `features`. `channel/videos` takes `tab=videos` (default), `shorts`, or `streams`, plus an optional `sort` (`latest`/`popular`/`oldest`).

> **Naming:** `/video/metadata` was previously `/video/info`. The old path still works but is deprecated — use `/video/metadata`.
