## 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 x402helper-settle-check-endpoint-0a391096
```

Example prompt: Before my agent pays to call https://api.example.com/data, can you check that x402 route and tell me its USDC price, whether it passes OFAC screening, and if billing looks valid?

## When to prefer this

Use this endpoint when an AI agent needs to pre-flight check an x402-protected route before paying — specifically to confirm the USDC cost, validate OFAC compliance, and verify billing configuration. Prefer this over generic HTTP inspection when the route uses the x402 payment protocol and you need structured compliance and rate data.

## Known failure modes

- Missing or invalid 'url' query parameter returns an error
- Non-x402 URL provided returns empty or failed result
- OFAC screening failure flags the route as blocked
- Network timeout if the target route URL is unreachable
- Malformed URL causes parsing error in response

## How this service works

X402 micropayments server — AI agents pay USDC for OFAC screening, rates, and billing verification.

## Output

Returns a JSON object with a 'success' boolean and a 'result' object containing payment rate, OFAC screening outcome, billing verification status, and other route metadata for the queried x402 URL.
