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.

Field inside data	Type	Meaning
`active_count`	`number \| null`	Optional active count supplied by this operation. Null means unknown.
`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[].address`	`string \| null`	Optional address supplied by this operation. Null means unknown.
`items[].appointed_on`	`string \| null`	Optional appointed on supplied by this operation. Null means unknown.
`items[].country_of_residence`	`string \| null`	Optional country of residence supplied by this operation. Null means unknown.
`items[].date_of_birth`	`object \| null`	Optional date of birth supplied by this operation. Null means unknown.
`items[].date_of_birth.month`	`number \| null`	Optional month supplied by this operation. Null means unknown.
`items[].date_of_birth.year`	`number \| null`	Optional year supplied by this operation. Null means unknown.
`items[].name`	`string \| null`	Optional name supplied by this operation. Null means unknown.
`items[].nationality`	`string \| null`	Optional nationality supplied by this operation. Null means unknown.
`items[].role`	`string \| null`	Optional role supplied by this operation. Null means unknown.
`resigned_count`	`number \| null`	Optional resigned count supplied by this operation. Null means unknown.
`total_results`	`number \| null`	Optional total results 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
