## 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 ontario-protocol-x402-agent-reputation-checker-0fdee5e4
```

Example prompt: Can you check the x402 reputation and payment readiness report for agent ID 'agent.example' using the Ontario Protocol checker before I enable payments for it?

## When to prefer this

Use this endpoint when you need to verify an agent's reputation or x402 protocol readiness before initiating or accepting payments. Prefer this over generic HTTP 402 testers when you specifically need agent-level reputation scoring tied to an agent ID within the Ontario Protocol ecosystem.

## Known failure modes

- Invalid or malformed agent_id returns an error or empty reputation object
- Unknown agent_id may return a null or empty reputation record
- Rate limiting or service unavailability returns a non-200 HTTP response
- Improperly formatted agent_id in the path parameter causes a 400 Bad Request

## How this service works
