# Maiat Protocol Trust Score Lookup

> Maiat Protocol Trust Score Lookup is a paid API for AI agents from app.maiat.io, paid per call via x402, $0.02/call, status unknown (last checked 2026-09-14).

Looks up the on-chain trust score, completion rate, and verdict for an Ethereum address representing an AI agent or token

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 maiat-protocol-trust-score-lookup-a92f1fa0
```

Example prompt: Before we hire that autonomous agent, can you check its Maiat trust score for the address 0x4a9f...3b2c and tell me if the verdict is safe to proceed?

## When to prefer this

Use this endpoint when you need to verify the on-chain reputation of an autonomous AI agent or token before delegating work or making payments to it, especially within ACP (Agent Commerce Protocol) ecosystems. Prefer this over generic identity lookups when you specifically need job-completion history and a trust verdict tied to an Ethereum address.

## Known failure modes

- Invalid or malformed Ethereum address returns an error or empty result
- Unknown address with no on-chain history may return a low/null trust score
- Network or blockchain node unavailability causes timeout or 5xx error
- Payment of $0.02 USDC not fulfilled causes 402 Payment Required response

## How this service works

The decentralized truth layer. Verifying the future of autonomous agents and trust.

## Output

Returns a JSON object with a human-readable summary (e.g. 'Reliable ACP agent — 42 jobs, 95% completion'), a verdict ('proceed' or similar), total jobs completed, a numeric trust score (0-100), and a completion rate (0-1 float).
