When to use this API

Prototyping auth systems

Quickly create tokens with different roles (admin, editor, viewer) to prototype role-based access control before building a full auth service.

Frequently asked questions

Should I use this in production?

This endpoint is designed for testing and prototyping. In production, sign JWTs on your own server using your private key.

Which signing algorithm is used?

The API uses HS256 (HMAC-SHA256). Asymmetric algorithms like RSA or ECDSA are not supported.

How do I set the token expiry?

Pass expires_in as a number of seconds. For example, 3600 for 1 hour, 86400 for 1 day. If omitted, the token defaults to a 1-hour expiry.

Is the iat (issued at) claim added automatically?

Yes. The API automatically adds the iat claim with the current timestamp.
