How it works
- Send your key in the X-API-Key header to https://data.fastsocial.co/v1/…
- Every answer is JSON with ok, data, and meta showing the credits it cost and what you have left.
- Failed calls are refunded; a real "not found" counts as an answer.
- Lists page with cursor: pass the one from the last answer.
