## 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-a2a-ready-evidence-capability-dd2e67dd -d '<json body>'
```

Example prompt: Can you check whether https://api.example.com/my-service is ready for agent-to-agent use and give me the evidence report?

## When to prefer this

Use this endpoint when you need programmatic, paid-per-call evidence that a given public URL supports agent-to-agent (A2A) communication patterns — especially in automated pipelines where you need a machine-readable validation report rather than a manual inspection. Prefer this over generic uptime checkers when A2A compatibility semantics matter.

## Known failure modes

- Invalid or unreachable URL returns an error response
- Non-public or firewalled URLs may fail accessibility checks
- Malformed URL format causes schema validation rejection
- Payment failure via x402 protocol prevents request from being processed
- Service unavailability on the Cloudflare Worker side causes 5xx errors

## 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, a 'data' object containing the A2A readiness evidence details for the submitted URL, and a 'capability' field confirming the endpoint name ('mg-a2a-ready-evidence').
