Frequently Asked Questions

For Free and Pro plans, requests are blocked when you hit your monthly limit. For Business plans, overage is automatically billed at $0.001 per additional request. Enterprise customers have custom overage pricing. We'll send you alerts at 80%, 90%, and 100% of your limit.

When you choose yearly billing, you pay for 10 months and get 2 months free. For example, Pro yearly is $490 instead of $588 (12 × $49), saving you $98. This is our way of rewarding long-term commitments.
RBAC allows you to assign different permissions to team members. For example, you can have Admins who can manage billing and API keys, and Members who can only view usage and make API calls. This is available on Business and Enterprise plans.
You can set up email or webhook alerts to notify you when your usage approaches your plan's rate limits. This helps you avoid service interruptions and plan upgrades proactively.
Yes, Enterprise customers can choose where their data is stored to comply with regional regulations like GDPR. We support data residency in multiple regions.
Overage is available exclusively on Business and Enterprise plans. For Business, overage is automatically billed at $0.001 per additional request. Enterprise customers have custom overage pricing. Free and Pro plans have a hard stop when the monthly limit is reached.
No, unused requests do not roll over to the next month. However, we'll notify you at 80%, 90%, and 100% of your limit so you can upgrade before hitting the cap.
