How credits are settled
- Submission: your balance must cover the requested
sample_size, otherwise the request is rejected with402. - Reservation: when sampling starts, credits are reserved for the number of respondents that can actually be sampled.
- Consumption: credits are consumed per successful respondent as sampling progresses.
- Settlement: unused reserved credits are released back. The final balance is reported as
credits_leftin the completed result.
If some respondents fail during sampling, you are only charged for the successful ones. A failed pipeline releases its full reservation.
