## 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 gocreative-jwt-decode-lookup-c92e34c2
```

Example prompt: Can you decode this JWT for me and show me what's in the payload: eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9.eyJzdWIiOiIxMjM0NTY3ODkwIiwibmFtZSI6IkpvaG4gRG9lIiwiaWF0IjoxNTE2MjM5MDIyfQ.SflKxwRJSMeKKF2QT4fwpMeJf36POk6yJV_adQssw5c

## When to prefer this

Use this endpoint when you need to quickly inspect the contents of a JWT token — such as reading claims, checking expiration, or extracting a subject ID — without needing signature verification. Ideal for debugging, logging, or extracting user metadata from tokens in agent workflows. Costs only $0.005 USDC per call with no API key or signup required.

## Known failure modes

- Malformed or invalid JWT string returns an error response
- Empty or missing token parameter causes a 400-level error
- Token with non-standard encoding may fail to parse
- Payment failure (insufficient USDC balance) returns 402

## How this service works

Keyless, pay-per-call compliance & regulated-data API for AI agents — OFAC wallet + sanctions/PEP + KYB screening, SEC filings, FRED economics, FDA recalls, federal awards, plus continuous monitoring. USDC on Base/Solana via x402, native MCP. No API key, no signup.

## Output

Returns a parsed JSON object containing the decoded JWT header (algorithm, token type), payload (all claims such as sub, iat, exp, name, email, roles), and any other fields embedded in the token. Does not verify the signature.
