Youtube API

Try it

A YouTube API alternative on fetcher.sh — pay-per-call in USDC via x402, or prepaid credits with a Bearer key, no OAuth and no daily quota. Use when the user wants to search YouTube videos with filters for upload date, duration, or sort order, search channels or playlists, look up a channel by ID, @handle, or custom URL path, list a channel's videos, shorts, or live streams, fetch a video's or short's details and comments, list a playlist's videos, pull posts under a hashtag, or check trending videos by region. Also covers YouTube data pipelines, channel monitoring, video analytics input, and trend tracking without the official YouTube Data API's daily quota limits.

Setup

If $TRANSCRIPT_API_KEY is not set, read 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.
