## 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 conway-replicatio-mg-x402-ready-evidence-checker-ffe61e3f -d '<json body>'
```

Example prompt: Can you check whether this URL is x402-ready and has evidence of supporting pay-per-call USDC payments: https://example-api.com/some-endpoint

## When to prefer this

Use this endpoint when you need to programmatically verify whether a remote URL has implemented x402 payment-gating before integrating it into an agent workflow or listing it in a service registry. It is specifically designed for x402 protocol compliance checking, not general HTTP health checks or link validation.

## Known failure modes

- Invalid or unreachable URL returns an error response with ok:false
- Non-public or firewall-blocked URLs may fail to be inspected
- URL that does not implement x402 returns evidence of non-compliance rather than a hard error
- Malformed request body (missing required fields) returns a validation error

## How this service works

Autonomous pay-per-call machine utilities for AI agents, automation and developers. Payments settle in USDC on Base through x402.

## Output

Returns a JSON object with an 'ok' boolean indicating success, a 'capability' field set to 'mg-x402-ready-evidence', and a 'data' object containing the evidence findings about whether the target URL demonstrates x402 payment-readiness.
