# AgentEconomy Rating API

> AgentEconomy Rating API is a paid API for AI agents from agenteconomy.report, paid per call via x402, $0.005/call, status unknown (last checked 2026-09-14).

Returns a real-time operational trust rating (AAA–D scale) for any x402 service, including tier, outlook, flags, uptime, paying agents, settled USDC, and network centrality.

## Facts

- Endpoint: POST https://agenteconomy.report/api/rating/:host
- Price: $0.005/call
- Payment: x402
- Status: unknown
- Last checked: 2026-09-14

- Structured record (JSON): https://api.zero.xyz/v1/capabilities/cap_ZELZf9dZn0PV94LrM_T_U

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 agenteconomy-rating-api-62c85f07 -d '<json body>'
```

Example prompt: Before I pay that x402 endpoint, can you pull the agenteconomy.report trust rating for api.someservice.xyz — I want to see the tier, outlook, uptime, and how many real paying agents have used it?

## When to prefer this

Use this endpoint when an AI agent needs to vet an x402 micropayment service before authorizing payment, or when building a trust-aware routing layer for agent fleets. Prefer it over generic uptime monitors because it combines on-chain settlement data (real economic activity) with liveness probes and Sybil-resistance checks across four blockchains — giving a credit-rating-style signal rather than just ping/pong availability.

## Known failure modes

- Unknown host — service has never been observed settling on supported chains, returns 404 or empty rating
- Rate limit exceeded — too many calls in a short window
- Service is newly listed and has insufficient data for a full rating — may return a provisional or incomplete response
- Host parameter malformed — returns 400 bad request

## Output

A JSON object containing the service's current trust tier (AAA to D), outlook (positive/stable/negative), any risk flags, uptime percentage, count of organic paying agents, total settled USDC across Base/Polygon/Arbitrum/Solana, and network centrality score — computed as of today's daily on-chain settlement analysis.
