Response

Response fields and example

This example is illustrative, not a captured live response. Variable-cost operations may settle a charge different from the list price below. A successful response puts the platform payload in data and reports the exact credits used, remaining balance, request id and cache status beside it.

The example is illustrative and shows a documented subset of data. The fields below are optional across supported sources; nullable fields can also be absent. Preserve unknown values and accept additional fields.

Schema basis: observed response shapes, not an exhaustive field specification. See schema coverage and validation limits.

Download the data JSON Schema. Validate response.data, not the whole envelope. A valid shape does not establish that every field or source record was returned.

The example is invented and illustrates types only; zero and empty values are not claims about a real result.

Failures use the typed error envelope. A confirmed uncharged or refunded failure reports zero; a pending reconciliation can report an unknown charge. Read credits_used and error.details.billing_status, and keep request_id for recovery. Response contract · Error reference
