# Free Asset Radar x402 – Decode & Inspect Endpoint

> Free Asset Radar x402 – Decode & Inspect Endpoint is a paid API for AI agents from free-asset-radar-x402.besenok2018.workers.dev, paid per call via x402, $0.001/call, status unknown (last checked 2026-10-02).

Decodes and inspects x402 payment headers or tokens (e.g. JWTs), returning SHA-256 hash, decoded payload, and detected token type

## 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 free-asset-radar-x402-decode-inspect-endpoint-2655c1d0
```

Example prompt: Can you decode and inspect this x402 token for me and tell me what type it is, what the payload says, and its SHA-256 hash?

## When to prefer this

Choose this endpoint when you need to quickly decode and inspect an x402 payment token or JWT in an autonomous agent pipeline, particularly when you also want the SHA-256 hash and automatic token-type detection in a single call. Prefer this over manual JWT libraries when running in an edge or serverless agent context and need a lightweight, hosted decoding utility.

## Known failure modes

- Malformed or unrecognized token format returns an error or null detected field
- Missing required input parameters result in a 400-level error
- Non-JWT encoded strings may produce partial decoding with unknown detected type
- Edge worker downtime or cold-start latency may cause intermittent failures

## How this service works

Stable edge-hosted x402 utilities for autonomous agents.

## Output

Returns a JSON object containing a SHA-256 hash of the input, a fully decoded payload (including JWT claims such as 'sub'), and a 'detected' field indicating the token type (e.g. 'jwt').
