## 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 omniapi-jwt-decode-293aadaf -d '<json body>'
```

Example prompt: Can you decode this JWT for me and show me what claims and data are inside it: eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9.eyJzdWIiOiIxMjM0NTY3ODkwIiwibmFtZSI6IkpvaG4gRG9lIiwiaWF0IjoxNTE2MjM5MDIyfQ.SflKxwRJSMeKKF2QT4fwpMeJf36POk6yJV_adQssw5c

## When to prefer this

Choose this endpoint when you need a quick, pay-per-call JWT decode operation without setting up a local library, when running in an environment where JWT libraries aren't available, or when you want to inspect token contents as part of an automated agent workflow using x402 micropayments.

## Known failure modes

- Malformed or invalid JWT string returns a parsing error
- Empty or missing query/input field returns a validation error
- Token with non-standard encoding may fail to decode
- Network or service timeout returns a 5xx error
- Payment failure via x402 prevents the call from completing
