## 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 rooms-by-aurmada-x402-trust-check-884c3f21
```

Example prompt: Before I pay for that x402 API, can you run a trust check on https://api.example.com/data and tell me the price, network, payTo address, and overall trust score?

## When to prefer this

Use this endpoint when an AI agent or user needs to vet an x402-gated resource before committing payment — especially when integrating a new third-party x402 API, when the price or network details seem unexpected, or when you want an independent probe-based trust score rather than trusting the provider's own documentation.

## Known failure modes

- URL does not return a 402 response — score penalized or check fails
- Endpoint is unreachable or times out — response time factor marked invalid
- Bazaar listing not found for the URL — listing-match factor cannot be evaluated
- Malformed or non-standard 402 response — fields may be missing from output
- Invalid URL format supplied — request rejected with validation error

## How this service works

Rooms is one shared space for you, your people, and everyone's AI.

## Output

Returns a 0–100 trust score with per-factor breakdown covering: whether the endpoint returns a valid 402, the price/asset/network/payTo it requests, its response time, whether those details match the public Bazaar listing, and historical probe data. Not a payment guarantee.
