Will this work with any API?

It works with CORS-enabled endpoints. If the API doesn't allow cross-origin requests, you'll get a CORS error. Most public APIs support CORS.

Is my data sent through your servers?

No. Requests go directly from your browser to the target URL. Nothing passes through our servers.

Can I test authenticated endpoints?

Yes. Add your Authorization header (Bearer token, API key, etc.) in the custom headers section.
