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.

200 · application/json

{
  "success": true,
  "platform": "booking",
  "endpoint": "/v1/booking/hotel-rooms",
  "data": {
    "_warnings": [],
    "checkin": "example",
    "checkout": "example",
    "count": 0,
    "currency": "example",

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.

Field inside data	Type	Meaning
`_warnings`	`array \| null`	Source array was empty in the reviewed captures; item fields remain unspecified.
`checkin`	`string \| null`	Optional checkin supplied by this operation. Null means unknown.
`checkout`	`string \| null`	Optional checkout supplied by this operation. Null means unknown.
`count`	`number \| null`	Number of records in this response, not lifetime or total matches.
`currency`	`string \| null`	Optional currency supplied by this operation. Null means unknown.
`hotel_id`	`string \| null`	Optional hotel id supplied by this operation. Null means unknown.
`max_rooms_per_booking`	`number \| null`	Optional max rooms per booking supplied by this operation. Null means unknown.
`offers`	`array \| null`	Source array was empty in the reviewed captures; item fields remain unspecified.
`platform`	`string \| null`	Optional platform supplied by this operation. Null means unknown.
`rooms`	`array \| null`	Source array was empty in the reviewed captures; item fields remain unspecified.
`sold_out_rooms`	`array \| null`	Source array was empty in the reviewed captures; item fields remain unspecified.
`type`	`string \| null`	Optional type 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
