Response fields

Business data is in results. The table lists the fields a record can contain; values the source does not provide are never made up.

Errors and billing

401

Missing or invalid key. Authentication runs before parameter checks, so unauthenticated requests never see the parameter schema.

422

Wrong parameter name or value. The error lists the parameters and allowed values this capability accepts and the closest match; it happens before any charge.

402

Insufficient balance. Top up first.

429

Per-minute request limit reached. Wait for Retry-After and try again.

503

Could not complete right now. Any charge for the call goes back to your balance automatically, and the billing receipt in the response states the actual outcome, including when it is not yet known. Do not resend blindly.

200 empty

The request completed without data and is not charged (billing.reason = empty_result_refunded).
