Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## 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-humanizer-4f29e569 -d '<json body>'
```

Example prompt: Can you decode this JWT for me and show me its claims with the expiration time in a readable format? Here's the token: eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9.eyJzdWIiOiJ1c2VyXzEyMyIsImV4cCI6MTcwMDAwMDAwMH0.signature

## When to prefer this

Choose this endpoint when you need a quick, lightweight decode of a JWT's payload claims — especially to humanize the exp timestamp — without caring about signature verification. Ideal for debugging, logging, or agent workflows that need to inspect token metadata (subject, expiry) before deciding whether to re-authenticate. Prefer this over full JWT verification libraries when you don't have the secret/public key available or when signature validity is handled elsewhere.

## Known failure modes

- Malformed JWT string (not three dot-separated base64 segments) — returns parse error
- Missing jwt field in request body — validation error
- JWT with no exp claim — exp_human field may be absent or null
- Network timeout — retry with same input
- Payment failure — 402 response if USDC balance insufficient

## How this service works

Decode JWT payload claims without signature verify. Call when inspecting exp/iat for debugging (untrusted decode). Returns claims and exp_human if present as deterministic JSON for $0.001 USDC via x402 on Base. First-party local math only—no RPC, live market feed, API keys, storage, or mediagen. Advisory only; the caller owns capital, risk, and production controls.

## Output

Returns a JSON object containing the decoded JWT claims (e.g. exp, sub) as-is, plus a human-readable ISO 8601 string for the expiry timestamp (exp_human), and a schema identifier. No signature verification is performed.
