## 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 agentledger-conformance-check-f29aaab5
```

Example prompt: Check whether my AgentLedger wallet endpoint at https://agent402.tools/api/uuid is properly x402-compliant — I want to see if it passes all conformance checks, including whether it responds with a valid 402 payment envelope and how many payment offers it exposes.

## When to prefer this

Use this endpoint when you need to programmatically verify that an AI agent wallet API correctly implements the x402 payment protocol — especially before deploying agent wallets powered by Coinbase CDP, Privy, Turnkey, or MetaMask into production. Prefer this over manual testing when you want a structured, machine-readable conformance report with pass/fail details per check.

## Known failure modes

- Target endpoint is unreachable or returns a network error — conformance report may show all checks failed
- Target endpoint does not implement x402 at all — all checks fail with descriptive detail messages
- Malformed URL provided — may return an error or empty result
- Target endpoint is rate-limiting the conformance checker — intermittent failures
- Endpoint behind authentication may not respond correctly to unauthenticated conformance probes

## How this service works

Set spending limits, budgets, approvals and audit trails on every AI agent wallet — Coinbase CDP, Privy, Turnkey, MetaMask. Non-custodial agent wallet management.

## Output

A JSON object containing the tested URL, total number of conformance checks run, an array of individual check results (each with an id, pass/fail status, title, and detail string), a count of passed checks, and a timestamp of when the measurement was taken. Useful for understanding x402 protocol compliance at a glance.
