Frequently Asked Questions
What counts as a chart request?
Each API call to generate a chart counts as one request. Cached responses don't count against your limit.
Can I upgrade or downgrade anytime?
Yes! You can change your plan at any time. When upgrading, you'll be charged a prorated amount. When downgrading, you'll receive credit toward future billing.
What happens if I exceed my limit?
We'll notify you when you reach 80% of your limit. If you exceed it, requests will return a 429 error until the next billing cycle or until you upgrade.
Do you offer refunds?
Yes, we offer a 30-day money-back guarantee. If you're not satisfied, contact us for a full refund.
What payment methods do you accept?
We accept all major credit cards (Visa, Mastercard, American Express) via Stripe. Enterprise customers can pay via invoice.
