jwt decode
Decode a JWT to see its header and payload, including human-readable expiry (and whether it is already expired). Does NOT verify the signature — decoding is safe to do on a token you are debugging; verification needs the secret and must happen in your own service. One URL. No install, no API key, free during the beta.

Call it
