What does the generated cURL command do?

A curl invocation with `-H 'Authorization: Bearer '` plus any other headers, method, and body you specify. Copy/paste into a terminal to hit the API with the token.

Can I include a request body?

Yes — paste JSON and it becomes a `-d` flag with proper escaping. Automatic content-type header unless you override.

Does it work with custom auth schemes?

The default is Bearer. Toggle to `JWT`, `Token`, or a custom scheme name for APIs that don't use Bearer.

Is the token stored anywhere?

No — it's in the generated command you copy. The tool itself doesn't persist anything. Don't commit the resulting curl command to git.

Fun Facts

JSON Web Tokens (JWT) were standardized in RFC 7519 in May 2015, authored by Michael Jones, John Bradley, and Nat Sakimura.
A JWT has exactly three Base64url-encoded parts separated by dots: header, payload, and signature — no more, no less.
The cURL command-line tool was first released by Daniel Stenberg on March 20, 1998, and now handles over 10 billion daily requests worldwide.
