Sonatype Nexus Repository OSS Requests Per Day: Hard Limit?

What counts towards a “daily request”?

When I use uv (instead of pip), the application makes a lot of requests to look at package metadata (which seems to be coming up as a HEAD request) to compare version data and compatibility with each other. Do those HEAD requests count towards the hard limit?

My CI usage seems to be using a lot more requests than I would expect, even when I’ve cached all the packages I would use locally. I’m trying to figure out where these requests are coming from.
