Access and Authentication

In order to access the API you must have a QUERY-KEY that is meant to be used in an authorization header.

All queries go through the following API endpoint URL:

https://apibl.spamhaus.net/lookup/v1/

Please note all requests MUST be sent over HTTPS and include an authorization header.

The authorization header has the format:

Authorization: Bearer [QUERY-KEY]

Ensure [QUERY-KEY] is replaced with the proper QUERY-KEY (no brackets [ ]) located in your Spamhaus account.
