## 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 agent-reputation-scorer-7b8da05e -d '<json body>'
```

Example prompt: Can you score the reputation of this agent — here's its input (a POST request body it received) and output (the response it returned) — and tell me how trustworthy or reliable it seems?

## When to prefer this

Use this endpoint when you need to programmatically assess the trustworthiness or reliability of an AI agent based on its observed behavior (input/output pairs). Prefer this over manual review when building automated agent pipelines, agent marketplaces, or multi-agent orchestration systems where you need a fast, paid reputation signal before trusting a new agent.

## Known failure modes

- Missing required 'input' or 'output' fields returns a validation error
- Malformed JSON body causes a 400 bad request
- Input type not set to 'http' or method not set to 'POST' may cause rejection
- Payment not included or invalid x402 payment header returns 402 Payment Required
- Service unavailability returns 5xx errors
