## SKILL.md

# 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.
