# TranscriptAPI

Full YouTube data toolkit via [TranscriptAPI.com](https://transcriptapi.com). Transcripts, search, channels, playlists — one API key.

## 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.

## Auth

All requests: `-H "Authorization: Bearer $TRANSCRIPT_API_KEY"`

## Endpoints

Channel endpoints accept `channel` — an `@handle`, channel URL, or `UC...` ID. No need to resolve first. Playlist endpoints accept `playlist` — a playlist URL or ID.
