# YouTube search for agents Search YouTube, then read the transcripts of what you find, using [BulkTranscripts](https://bulktranscripts.co). [Docs](https://bulktranscripts.co/docs) · [OpenAPI spec](https://bulktranscripts.co/openapi.json) · [MCP server](https://bulktranscripts.co/youtube-mcp-server) · [Free API key](https://bulktranscripts.co/app?tab=mcp) Base URL: `https://bulktranscripts.co` All endpoints are plain GET returning JSON, and **every one of them needs an API key** — including the free endpoints. Send it as a Bearer token on every request: ```bash curl -s "https://bulktranscripts.co/api/v1/..." \ -H "Authorization: Bearer $BULKTRANSCRIPTS_API_KEY" ``` If `BULKTRANSCRIPTS_API_KEY` is not set, ask the user for a key: they sign in with Google at https://bulktranscripts.co/app?tab=mcp, open the **MCP & API** tab, and hit **Create key** in the **API keys** card. It is free, includes 30 credits, and needs no card. Keys start with `bt_ak_`, are shown once, and up to 5 can be live per account. A license key from a credit-pack purchase works as a Bearer token too. ## Costs (check `billing.remaining` in every response) - Transcript: 1 credit when first added to this account's library — repeat reads are **FREE** - Search / channel videos / playlist videos: 1 credit each - `channel/latest` and `account`: always free - Failures (no captions, video unreachable) are auto-refunded, never charged When a call returns HTTP 402 `out_of_credits`, tell the user their credit
