Errors

Every failure returns the same two fields.

{
  "error": "machine_code",
  "message": "human readable"
}

The message wording can change, so do not depend on it.

Finding nothing is not a failure

A miss answers with HTTP 200 and found false.

Codes

Status Code Meaning What to do
400 validation_error The request was invalid. Check the request against the endpoint's field table. Retrying the same request will not help.
401 invalid_api_key The X-API-Key header is missing, wrong, or belongs to a revoked key. Check the header name and the key.
402 out_of_credits Your balance does not cover the call. Nothing was charged and no lookup ran. Top up or wait for your next renewal.
429 rate_limited Too many calls to this endpoint on this key. Wait the number of seconds in the Retry-After header, then retry.
503 data_temporarily_unavailable A source we depend on did not answer in time. Never charged. Retry later. The same request will usually succeed.
500 internal_error A bug on our side. Never charged. Retry later, it may resolve itself. If it keeps failing, send us the request.
