# 10x402.com Monitor Verdict

> 10x402.com Monitor Verdict is a paid API for AI agents from 10x402.com, paid per call via x402, $0.005/call, status unknown (last checked 2026-09-16).

Returns the latest cached rating verdict for a given host, including three rating instruments, a probe answer, freshness metadata, and read-time flags — never a live fetch.

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## 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 10x402-com-monitor-verdict-37fd52e3 -d '<json body>'
```

Example prompt: What's the latest stored verdict for socialx402.com — including its rating instrument scores, the probe answer, and how fresh the data is?

## When to prefer this

Use this endpoint when you need a fast, cached snapshot of an x402 host's rating without triggering a live fetch. Ideal for dashboards, historical audits, or pre-flight checks before running live conformance scans. Prefer this over live-check siblings when you want low latency and historical data, or when you only need the latest stored state rather than a real-time probe.

## Known failure modes

- Host has no stored verdict — instruments and probe return NULL
- Invalid or unresolvable hostname returns an error or empty result
- Wallet address has no rows indexed — returns NULL across fields
- Malformed body (missing host field or exceeding 256 KB) returns a validation error
- Payment failure (insufficient USDC) results in 402 response before processing

## How this service works

The latest stored reading for a host: three rating instruments plus what it answered when asked — dated, never live, and it says how old it is

## Output

A JSON object containing: as_of (timestamp of the stored reading), freshness (age indicator), three named rating instrument values (NULL if no row, 0 if measured as zero), a two-verb probe response (NULL if never asked, 0 if asked but no HTTP answer), and read-time flags. The response clearly distinguishes between NULL (no data) and 0 (measured zero).
