Hi @hnje,
Thanks for joining the Community!
It’s possible that your requests are hitting the rate limit for the Management API. You can find those details here: Management API Endpoint Rate Limits
Have you tried adding the per_page parameter? You can include up to 100 entries per page, so you should be able to request twice as many entries per request.
Also, if there are any log types you are not interested in, you can add a q parameter to filter them out using Lucene Query Syntax
