YouTube API
YouTube data on demand: video/channel/playlist search with real filters (upload date, duration, sort order), channel and video lookups, videos, shorts, live streams, playlist contents, comments, hashtag feeds, and trending — one plain HTTP GET per call, paid as you go. No developer console project, no OAuth consent screen, no daily quota.
Base URL: https://youtube.fetcher.sh
Authentication
Two ways to pay, same data — full mechanics in the `fetcher` skill:
# 1. Prepaid credits (recommended — get a key at https://fetcher.sh/topup
# or via POST /api/credits/topup, see the fetcher skill)
export FETCHER_API_KEY="bby_live_xxxxxxxxxxxx"
curl -H "Authorization: Bearer $FETCHER_API_KEY" \
"https://youtube.fetcher.sh/api/search/video?query=hello"
# 2. x402 pay-per-call — omit the header; a GET with no payment returns 402
# with machine-readable payment requirements (USDC on Base, Polygon,
# Arbitrum, Monad, or Solana). @x402/fetch signs and retries automatically.Every response is { "status": number, "message": string, "data": ... }; the HTTP status mirrors status.
Endpoints (15 — all GET, $0.005/call)
| Endpoint | What it returns |
|---|---|
/api/search/video | Videos matching a query; upload date, duration, sort filters |
/api/search/channel | Channels matching a query |
/api/search/playlist | Playlists matching a query |
/api/channel/{id} | Channel details by ID |
/api/channel/handle/{handle} | Channel details by @handle |
/api/channel/path | Channel details by custom URL path |
/api/channel/{id}/videos | A channel's videos |
/api/channel/{id}/shorts | A channel's shorts |
/api/channel/{id}/live-streams | A channel's live streams |
/api/video/{id} | Video (or short) details |

/api/shorts/{id} | Short details |
/api/playlist/{id}/videos | A playlist's videos |
/api/hashtag/{tag} | Videos under a hashtag |
/api/trending | Trending videos, optionally by region |
{id} / {handle} / {tag} are path parameters. Optional cursor / lang / geo refine results; query (search) and channelPath (path lookup) are required where they appear.
