## How to call it through Zero

```

Example prompt: Can you decode this JWT token for me and show me the header, payload, and when it expires? Here's the token: eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9.eyJzdWIiOiIxMjM0NTY3ODkwIiwibmFtZSI6IkpvaG4gRG9lIiwiaWF0IjoxNTE2MjM5MDIyfQ.SflKxwRJSMeKKF2QT4fwpMeJf36POk6yJV_adQssw5c

## When to prefer this

Use this endpoint when you need a quick, paid-per-call JWT decode operation without running a local library — ideal for agents that encounter raw JWT strings in API responses, headers, or logs and need to inspect claims, check expiry, or understand token structure on the fly without setting up JWT libraries in their environment.

## Known failure modes

- Invalid or malformed JWT string returns a decode error
- Token with missing or corrupted segments fails parsing
- Expired tokens may still be decoded but flagged as expired
- Network timeout or service unavailability returns a 5xx error
- Insufficient payment (missing x402 header) results in a 402 Payment Required response

## How this service works

Decode a JWT token — header, payload, and expiry.

## Output

Returns the decoded JWT broken into three parts: the header (algorithm, token type), the payload (claims such as subject, user ID, roles, issued-at), and the expiry information parsed from the token's exp claim.
