Questions before you ship.

How do I get access?

Sign up to get 500 free API credits with no card required, then create an API key in the dashboard. Send it in the X-API-Key header and you can make your first request in under a minute.

What counts as one request?

One HTTP call to one endpoint. Each request costs 2 credits, except channel info at 3, regardless of how many rows it returns. A search returning 10 results is still one request.

Do YouTube calls share credits with other Tapline APIs?

Yes. Your plan has one credit pool shared across every live Tapline API.

How many results does each endpoint return?

Search returns 10 results by default, comments 20, channel videos 30, and playlists up to 50; use the limit parameter to request a different amount. Metadata, transcript, subtitle tracks, formats, heatmap, and channel info are single-record endpoints.

Do failed requests cost anything?

No. Credits are charged only when a call reaches its target and returns data.

Is the data live or cached?

Calls return the current state at request time. Identical requests within a short window may be served from a brief cache.

Is Tapline affiliated with YouTube?

No. Tapline is independent. Data is sourced from publicly visible YouTube pages.

What happens when I hit the YouTube Data API quota?

The official API allocates 10,000 units a day across most endpoints plus a separate 100 search calls, and going above the default requires a compliance audit. Tapline meters the same work in credits against a monthly pool with no daily ceiling, so raising your limit is a plan change rather than an application.
