Frequently Asked Questions
Can I change plans later?
Yes! You can upgrade or downgrade your plan at any time. Changes take effect immediately, and billing is prorated.
What happens if I exceed my request limit?
We'll send you a notification when you reach 80% of your limit. On the Free plan, requests will be rate-limited. On paid plans, we offer overage billing at reasonable rates.
Is there a free trial for Pro?
Yes! Pro plans come with a 14-day free trial. No credit card required to start.
What payment methods do you accept?
We accept all major credit cards (Visa, Mastercard, Amex) and ACH transfers for annual Enterprise plans.
