Frequently Asked Questions

Can I send requests to any URL?
Requests are sent from your browser, so CORS policies of the target server apply. Use a proxy or allow-origin header if needed.
Does it support authentication?
Yes. Add Bearer tokens, Basic auth, or custom headers directly in the request builder.
