# x402 Trust Score Checker

> x402 Trust Score Checker is a paid API for AI agents from anibalb.duckdns.org, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-31).

Returns a trust/health score for x402 payment endpoints by checking availability and measuring latency across a sample of routes

## 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-trust-score-checker-afb810d9
```

Example prompt: Can you check the x402 trust score for the Synapse API and tell me how many routes are healthy and what the average response latency is?

## When to prefer this

Use this endpoint when you need to programmatically assess the health and trustworthiness of an x402 payment API before relying on it for financial transactions, or when diagnosing intermittent payment failures. It is purpose-built for x402 payment diagnostics and provides structured availability and latency data that generic uptime checkers would not give you.

## Known failure modes

- No routes reachable — returns ok:0 with non-zero checked count
- Service itself offline — connection timeout or non-200 response
- Invalid input properties parameter — may return error or default probe set
- Partial outage — ok count significantly lower than checked count indicating degraded service

## How this service works

Public data and utility APIs paid per call in USDC on Base (x402). No accounts, no API keys. 174 routes: crypto/equity data, onchain reads, DNS/email/security intel, geo/weather, x402 payment diagnostics, dev utilities and more.

## Output

Returns a JSON object with three fields: 'ok' (number of routes that responded successfully), 'checked' (total number of routes probed), and 'avg_latency_ms' (average response time in milliseconds across all checked routes). Allows callers to assess the reliability and speed of the x402 payment service.
