Frequently asked questions

What authentication methods are supported?

Bearer token (Authorization: Bearer ...), Basic auth (username:password encoded), and custom headers for API key auth.

Are my credentials sent anywhere?

No — the command is generated entirely in your browser. Your auth tokens and passwords never leave your tab.

Does this actually execute the request?

No — this is a command generator only. Copy the command and run it in your terminal. For in-browser testing use the API Tester tool.

Can I generate curl for multipart form data?

Select "Form data" body type to generate -F flags for multipart/form-data requests.
