YouTube API · Video Transcript
Video Transcript
The full transcript of any video as timestamped plain text, in a single call.
Send a video id and get back the spoken transcript as timestamped lines (HH:MM:SS per line). When no transcript exists, `available` is false and the text is empty (still a billable 200). Ideal for summarisation, search indexing, subtitles and LLM pipelines.

FAQ
Questions before you connect?
Pricing & Balance
Every endpoint has a fixed per-request price in USD, shown on its docs page, and charged against your API balance, so you always know what each call costs.
YouTube charges far more underlying quota for search than for direct lookups. Video Search costs $0.01 / request; every other endpoint costs $0.003 / request.
No. Your API balance never expires, so you can use it whenever your workflows need it. In the unlikely event TubeField is ever discontinued, unused paid balance is refunded.
Paid API requests stop with a 402 until you add more balance. This keeps spend predictable and prevents unexpected charges.
API & Integration
Create and manage API keys from your account, then send your key in the X-API-Key header from your app, scripts, or internal tools.
Yes. Your dashboard shows every request, its cost, and your remaining balance, so you can track spend while building and running automated workflows.
Yes, a completed lookup is billable even when the answer is empty (for example a video with comments turned off). Errors like 402 or 429 are never charged.
We enforce a rate limit of 10 requests per second per API key. If you exceed it, the API returns HTTP 429. Build exponential backoff (briefly pausing before retrying) into your application code.
Our support team responds to email inquiries within 1 business day. We can help with account, billing, and API integration questions.
