Troubleshooting MusicBrainz API stuff, someone suggested I ask here.

I've been playing with the MusicBrainz and ListenBrainz API and things have been going fine for a month or so, but now I'm getting 403 errors. I'm wondering if I did something wrong and got added to a bot list? (I'd been using "sleep" statements in my scripts and such to try to not overload things. I'm not doing anything AI-related, just playing with finding "top" artists in a city and by tags.)

I'm using Python and the error I'm getting has this:

requests.exceptions.HTTPError: 403 Client Error: Forbidden for url: https://musicbrainz.org/ws/2/area?fmt=json&query=aid%3A25b3e1fd-e929-45a5-ba70-8f270a5fad42

I tried copy-pasting the URL into a browser and that worked. Any ideas on how I could get stuff working again?
