## 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-jwt-claims-audit-cde0d38c -d '<json body>'
```

Example prompt: Can you audit the claims in this JWT — check the claim names, expiry status, and identifiers as of epoch 1720000000, without returning any of the actual claim values?

## When to prefer this

Choose this endpoint when you need a stateless, privacy-preserving preflight audit of JWT claim metadata — specifically when you must not expose claim values, when you need deterministic expiry evaluation at an explicit reference time, or when integrating a lightweight JWT structure check into an enterprise agent workflow before a security, policy, or access-control decision.

## Known failure modes

- Missing or malformed claims object returns a validation error
- Invalid or missing now_epoch causes evaluation to fail or default unexpectedly
- Malformed JWT structure may result in parse errors
- Payment failure via x402 prevents execution
- Empty claims object returns minimal audit with no fields found

## How this service works

Audit JWT claim names, expiry, and identifiers at an explicit reference time without returning claim values. Use it as a bounded preflight or analysis step inside an enterprise agent workflow before data, policy, integration, security, or commercial decisions reach production. Returns deterministic machine-readable JSON for $0.003 USDC via x402 on Base. Execution is first-party, local-only, stateless, memory-only, and has no paid upstream or input retention. Results are advisory; the caller rem…

## Output

Returns deterministic machine-readable JSON listing the JWT claim names present, expiry evaluation result relative to the provided reference epoch, and identified identifier fields — without revealing any claim values. No data is retained or logged.
