## 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 x402-service-trust-oracle-cd837926
```

Example prompt: Before I pay for it, can you check whether this x402 endpoint is actually live, valid, and has a good reputation: https://some-service.example.com/data?

## When to prefer this

Use this endpoint before making a payment to an unknown x402 service to reduce risk of paying for a dead or fraudulent endpoint. Also use it to discover a curated list of working x402 services when you don't have a specific target in mind. Prefer this over cold-calling an x402 endpoint directly when trust and uptime matter.

## Known failure modes

- Queried endpoint URL is unreachable or malformed — returns invalid/down status
- Endpoint has no prior reputation data — returns unknown trust score
- Missing or invalid ?endpoint= parameter format — may return catalog instead of trust check
- Upstream probe timeout — liveness check may be stale or inconclusive

## How this service works

Оракул доверия к x402-сервисам: жив ли эндпоинт, валиден ли, репутация/аптайм, стоит ли платить (?endpoint=url). Без параметра — каталог реально рабочих сервисов

## Output

Returns trust metadata for the queried x402 endpoint: whether it is alive, whether it passes validity checks, its reputation score, and uptime history. When called without the endpoint parameter, returns a curated catalog of currently working and reputable x402 services.
