ip_lookup_unavailable

403. The key and the request were both fine. ?ip= is not available here.

{
  "error": {
    "code": "ip_lookup_unavailable",
    "message": "Address lookup is not available on this deployment."
  }
}

Why

Answering about an address other than the caller’s needs a geolocation dataset, which is a separate file from the API itself. When it is absent the parameter declines rather than returning nulls, because nulls would read as “we do not know that address” when the truth is that nobody asked.

Fix it

Nothing to fix on your side. It is a configuration state on ours, so tell us and include the time you tried.

Requests without ?ip= are unaffected, including everything about the caller.
