Hiya! We put that limit in place precisely for situations like yours - to find folks who have interesting use patterns. Most of them are attackers, so this stems the bleeding. You’re not, awesome!
We do have to ask you to upgrade, today, and we can raise the limit for you. You should already be on a pro plan since you are reselling our services and our terms of service are very specific that this is not permitted on the free tier.
Let me know when you’ve upgraded and I can raise the limit for you.
