# 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.

Source needs review
The tracked source changed or could not be synchronized. Review the current source before installing.
Review before install: Avoid automatic install
License: MIT
Listed tools are metadata hints, not tested compatibility. Agent prompts are suggested handoffs.
Check the source for dependencies, API keys and third-party costs. A public repository does not mean every service is free.
Repository metadata and review signals are advisory. Popularity, source discovery and successful execution are different facts.
Version reported in registry metadata; check source releases before relying on it.
