## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability coco-jwt-decode-348551a0
```

Example prompt: Can you check if this JWT token is expired: eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9.eyJzdWIiOiIxMjM0NTY3ODkwIiwibmFtZSI6IkpvaG4gRG9lIiwiaWF0IjoxNTE2MjM5MDIyfQ.SflKxwRJSMeKKF2QT4fwpMeJf36POk6yJV_adQssw5c?

## When to prefer this

Choose this endpoint when you need a lightweight, pay-per-call JWT decode and expiry check without setting up a local JWT library. Ideal for AI agents or serverless pipelines that need to quickly validate token status before making authenticated API calls, especially when the x402 micropayment model fits your cost structure.

## Known failure modes

- Malformed or non-JWT string passed as token — likely returns an error or unexpected result
- Missing token query parameter — request may fail validation
- Token with no expiry claim (no 'exp') — expired field behavior may be undefined
- Network timeout or service unavailability — no response returned

## Output

Returns a JSON object containing at minimum an 'expired' boolean indicating whether the provided JWT token has passed its expiration time. May also include decoded token claims or header/payload data.
