How many files (URLs) can be purged on a paid plan with one API call?

There was a similar question here How many paths can be purged with the API at once? , but the answer there points to a URL which does not exists any more.

No limits for URL purge is mentioned here https://developers.cloudflare.com/api/operations/zone-purge , and Purge by single-file (by URL) here https://developers.cloudflare.com/cache/how-to/purge-cache/#purge-by-single-file-by-url only have this:

The single-file purge rate limit for the Free subscription is 1000 urls/min. The rate limit is subject to change.

Tested on the Business plan and can confirm that 30 URLs per request is still correct.

Too bad that https://developers.cloudflare.com/api/operations/zone-purge only mentions tags, hosts, or prefixes, but not URLs:

You may purge up to 30 tags, hosts, or prefixes in one API call.

Also raised an support ticket and receive a confirmation from Cloudflare about 30 URLs per single API call limit.
