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.
{
"success": true,
"platform": "credits",
"endpoint": "/v1/credits/balance",
"data": {
"credits_remaining": 0,
"credits_lifetime": 0,
"updated_at": null,
"connection": {}
},
"credits_used": 0,
"credits_remaining": 99,
"request_id": "req_…",
"cached": false
}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: reviewed response shaper. 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.
| Field inside data | Type | Meaning |
|---|---|---|
credits_remaining | number | null | credits remaining |
credits_lifetime | number | null | credits lifetime |
updated_at | string | null | Nested response fields; optional unless explicitly documented. |
connection | object | null | Nested response fields; optional unless explicitly documented. |
Core response fields reviewed from the public response shaper. Fields vary by requested options; additive fields remain allowed.
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
