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": "polymarket",
"endpoint": "/v1/polymarket/research",
"data": {
"count": 0,

}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.

|---|---|---|
count | number | null | Number of records in this response, not lifetime or total matches. |
items | array | null | Returned records. Source coverage and completeness vary. |
items[].active | boolean | null | Optional active supplied by this operation. Null means unknown. |
items[].closed | boolean | null | Optional closed supplied by this operation. Null means unknown. |
items[].end_date | string | null | Optional end date supplied by this operation. Null means unknown. |
items[].event | object | null | Optional event supplied by this operation. Null means unknown. |

Optional fields reviewed from preserved successful responses. Additive fields and source variations remain allowed; validate the fields your workflow requires.
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
