YouTube Search

Search YouTube and fetch transcripts via TranscriptAPI.com.

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.

API Reference

Full OpenAPI spec: transcriptapi.com/openapi.json — consult this for the latest parameters and schemas.

GET /api/v2/youtube/search — 1 credit/page

Search YouTube globally for videos, channels, playlists, or movies.

curl -s "https://transcriptapi.com/api/v2/youtube/search?q=QUERY&type=video&limit=20" \
  -H "Authorization: Bearer $TRANSCRIPT_API_KEY" \
  -H "User-Agent: YourAgent/1.0"

Param	Required	Default	Validation
`q`	conditional	—	1-200 chars (trimmed), first page
`type`	no	`video`	`video`, `channel`, `playlist`, `movie` (first page)
`sort`	no	`relevance`	`relevance` or `views` (first page)
`upload_date`	no	—	`hour`, `today`, `week`, `month`, `year` — videos, first page
`duration`	no	—	`short` (<4m), `medium` (4-20m), `long` (>20m) — videos, first page
`features`	no	—	comma-separated: `hd`, `subtitles`, `cc`, `live`, `4k`, `hdr`, etc.
`limit`	no	`20`	1-50
`continuation`	conditional	—	token from a previous response (subsequent pages)

Provide exactly one of q (first page) or continuation (next pages) — the token already encodes the filters. sort/upload_date/duration/features apply to the first page only.

Find recent, most-viewed videos:

curl -s "https://transcriptapi.com/api/v2/youtube/search\
