    1. Is there an API endpoint available to see if a domain is in a web category, and return which ones it is in?
    2. Is there a reference document which summarises each of the web categories and the types of content in each? (some are obvious, but some - like gross - aren't clear and could be content across a broad spectrum given what's gross can be different from person to person.

    ---

    Long story short - I need to have a level of continuous assurance in place to test that domains in specific categories are being blocked.

    Nobody wants to sit there, connect to a SSID that applies a specific client role, and see what's returned manually - so I'd like to do this via API.

    However, haven't had any luck finding out if an API endpoint exists that I can programmatically ask "hey, is domain xyz.com blocked by one of your web categories, and if yes - which ones?"

    The end result of this is I can leverage the API to, on a regular basis, pass it a list of domains we want to be checking, and write the results back to a file for review, and driving any necessary action.

    Haven't had any luck with this, so appreciate any insight of the community on this.

    Thanks in advance :)

    The Brightcloud database is being used for web category lookups. They have a website to test the FQDN: https://brightcloud.com/tools/url-ip-lookup.php

    I don't believe Brightcloud offers an API to test an FQDN. 

    Another option is to use the UXI sensors. They can do automated testing and check if a website is being blocked.

    Thanks @willembargeman, appreciate that fast response and assistance.

    Wasn't the answer I was hoping for, but at least it's an answer I can bank on and confirmed what I already found.
