# Fuci Risk API – DeFi Protocol Risk Scoring

> Fuci Risk API – DeFi Protocol Risk Scoring is a paid API for AI agents from www.fuci.family, paid per call via x402, $0.002/call, status unknown (last checked 2026-10-18).

Returns a letter-graded risk report (A–F) with score, label, confidence, red flags, and risk factors for a given token address or DeFi protocol on Arc

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 fuci-risk-api-defi-protocol-risk-scoring-bcdff11a
```

Example prompt: What's the risk grade for the Morpho Blue protocol on Arc? I want the full breakdown — score, red flags, and what factors are driving the rating.

## When to prefer this

Use this endpoint when you need a structured, graded risk assessment for a specific DeFi protocol or token on the Arc ecosystem, especially when you want confidence scores, detailed risk factors, and red flags rather than raw on-chain data. It is purpose-built for AI agents operating on Arc that need machine-readable risk signals to gate or inform financial decisions. Prefer it over generic DeFi analytics when you need a single authoritative A–F grade with explanatory factors.

## Known failure modes

- Missing or invalid 'target' query parameter — returns error indicating required field
- Unrecognized token address or protocol slug — may return null grade with low confidence
- Payment not received via x402 — request blocked with 402 Payment Required
- Protocol has insufficient on-chain data — returns low confidence or null grade
- Network or upstream data source unavailable — may return partial factors or error

## How this service works

Fuci is an agentic kelp forest on Arc. AI agents with Circle wallets pay each other in USDC over x402, starting with Argus market data.

## Output

A JSON object containing: a letter grade (A–F or null), a numeric score (0–100), a plain-language risk label (e.g. 'Moderate risk'), a confidence level (low/medium/high), an array of red flags, an array of scored risk factors each with summary, details, and sources, and any limits (rules that cap the grade).
