Do I need a credit card to start?

No. The free tier gives you 100 API calls per month with no credit card required. Just sign up and get your API key instantly.

What are the rate limits?

Free: 100/mo, Hobby ($9): 5,000/mo, Pro ($29): 50,000/mo, Business ($99): 500,000/mo. All plans include access to every endpoint.

Can I use this in production?

You'll get a 429 response with your current usage. Upgrade anytime — changes take effect immediately with no downtime.

Do you support CORS?

Yes. All API endpoints return proper CORS headers, so you can call them from browser-side JavaScript in any web app.
