Errors

Every error is a problem object with a code and a next_step. Every response carries the RateLimit and RateLimit-Policy headers; see Rate limits.

Status	Problem codes	When
400	`invalid-request`, `idempotency-key-required`, `unsupported-version`	The request could not be read, or an Idempotency-Key is missing.
422	`validation-failed`, `quote-required`, `dataset-unavailable`	The request is not valid. errors lists every problem with a JSON pointer and did_you_mean.
429	`rate-limited`	Too many requests. Wait for Retry-After.
Any other failure	`internal-error`, `service-unavailable`, `tps-screen-expired`	Something failed on our side (500 internal-error) or the service is briefly unavailable (503 service-unavailable, with Retry-After). Nothing was charged; retry with the same Idempotency-Key. A count, sample, quote or order with telephone in play is also refused with 503 tps-screen-expired, with no Retry-After, while the dataset version's TPS and CTPS screen is more than 28 days old.
