## 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 agentreeve-reputation-api-b05efb83 -d '<json body>'
```

Example prompt: Before I pay for that x402 API at https://api.example.com/data, pull its AgentReeve reputation report so I can see its 30-day uptime, quote integrity, and whether its payTo address has been stable.

## When to prefer this

Use this endpoint when you need a history-based, signed reputation assessment of an x402 endpoint before committing to it as a dependency. It is ideal for pre-integration vetting, ongoing trust monitoring, or comparing multiple x402 APIs. Prefer /api/preflight instead if the endpoint is brand new (not yet indexed) and you need a live liveness check rather than historical analysis.

## Known failure modes

- Endpoint URL not in index: returns known:false — use /api/preflight for a live check instead
- Invalid or malformed URL input: returns a validation error
- x402 endpoint too new to have history: known:false with no historical data
- Network timeout or upstream probe data unavailable: service error response
- Payment not received or insufficient: request rejected at payment layer

## How this service works

Reputation report for an x402 endpoint. Signed 30-day reputation from probe history: uptime, strict-quote integrity, payTo stability, on-chain payer traction and longevity — with daily series and evidence. History-based: endpoints new to the index return known:false (use /api/preflight for a live check). Free compact score: GET /api/reputation?url=…

## Output

A signed reputation report including: a known flag (false if endpoint is new to index), overall reputation score, 30-day uptime percentage, strict-quote integrity rating, payTo address stability score, on-chain payer traction and longevity metrics, and daily time-series data with supporting evidence records.
