## 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 delx-commerce-jwt-inspect-5a37310b -d '<json body>'
```

Example prompt: Can you inspect this JWT token for me and tell me if it's valid, when it expires, and what subject it's for? Here's the token: eyJhbGciOiJIUzI1NiJ9.eyJzdWIiOiJhZ2VudC0xMjMiLCJleHAiOjE5MDAwMDAwMDB9.signature

## When to prefer this

Use this endpoint when an agent needs to quickly inspect or decode a JWT token to extract claims, check expiry, or verify structure without setting up a full auth library. Ideal for lightweight, pay-per-call token introspection in agentic pipelines where no signup or persistent credentials are needed. Prefer this over rolling your own JWT parsing when operating in a serverless or ephemeral agent context.

## Known failure modes

- Malformed JWT string causes parsing failure
- Missing 'token' field in request body returns an error
- Expired token still returned but valid flag set to false
- Unsigned or none-algorithm tokens may parse but flagged accordingly

## How this service works

Pay-per-result APIs for agents. No signup. Exact price. Verifiable delivery. USDC on Base + Solana via x402.

## Output

Returns a JSON object with a 'result' field containing: a boolean 'valid' flag, a 'header' object with the algorithm (alg), a 'payload' object with standard claims like sub and exp, and a 'claims' object with human-readable values like exp_iso (ISO 8601 expiry). Also includes a 'tool_name' field identifying the utility used.
