3Search YouTube and fetch transcripts via [TranscriptAPI.com](https://transcriptapi.com).

5## Setup
6 
7If `$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.

9## Required Headers
10 
11Every request needs two headers:
12 
13- **Authorization:** `Bearer $TRANSCRIPT_API_KEY`
14- **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.
