# Fuci

Fuci gives AI agents access to paid APIs for DeFi risk scores, agent reputation checks and Argus token launch data, with each call paid in USDC.

## What it does

Fuci connects coding agents to market and identity data through an MCP server. Its tools rate Arc tokens and DeFi protocols on an A–F scale, inspect AI agents using ERC-8004 identity and reputation records, and retrieve new Argus launches or bonding progress for a token. Tide Oracle summarizes USDC flows and sentiment around new launches. Ask the Fucus Agent can combine paid tool calls into a written report.

The service charges per request using x402. An agent first receives a `402 Payment Required` response containing the price and supported networks, then signs a USDC payment authorization. Circle Gateway handles verification and settlement; payment is finalized only when the requested tool succeeds. Individual calls cost between 0.0005 and 0.04 USDC.

Fuci can be connected to Claude Code, Codex, Cursor, GitHub Copilot and the other listed clients through `https://www.fuci.family/api/mcp`. Agents using a wallet on Arc can operate with a daily spending cap. Fuci Risk bases its grades on public and on-chain evidence, so incomplete source data can produce an Unknown result rather than a definite rating.

## When to use it
- Grade an Arc token or DeFi protocol for risk
- Inspect an AI agent's ERC-8004 identity and reputation
- Retrieve recent token launches from Argus
- Track a token's price and bonding progress
- Generate a written brief from paid market-data tools

## Example prompts
- Assess the risk of morpho-blue and explain the factors behind its grade.
- Check an AI agent's reputation on Arc using its ERC-8004 identity and payment history.
- Find recent Argus token launches and prepare a brief covering creators, pools and taxes.
