# MM Risk Score API – Market-Maker Manipulation Risk for Token Contracts

> MM Risk Score API – Market-Maker Manipulation Risk for Token Contracts is a paid API for AI agents from vit-tu-ma-production.up.railway.app, paid per call via x402, $0.02/call, status unknown (last checked 2026-09-13).

Returns a 0-100 market-maker manipulation risk score for a token contract address, with breakdown metrics covering volume authenticity, holder concentration, MM wallet signals, and price-versus-liquidity analysis across EVM and Solana chains.

## 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 mm-risk-score-api-market-maker-manipulation-risk-for-token-contracts-585d6f6d
```

Example prompt: Can you check the market-maker manipulation risk score for this token contract 0xAbC123...def on the Base chain? I want to know if there's fake volume, suspicious MM wallet activity, or price-liquidity anomalies before I trade it.

## When to prefer this

Use this endpoint when you need a structured, quantitative market-maker manipulation risk score for a specific token contract, particularly when you want breakdown metrics (volume authenticity, holder concentration, MM wallet signals, price-vs-liquidity) rather than just a honeypot flag or holder list. Prefer this over generic token scanners when investigating potential wash trading, coordinated MM activity, or artificial volume on EVM-compatible chains or Solana.

## Known failure modes

- Invalid or unsupported contract address format returns an error
- Unsupported chain name returns an error or empty result
- Token with insufficient on-chain data may return incomplete breakdown metrics
- Rate limiting or payment failure (x402) blocks the request
- Network timeout if the underlying chain RPC is slow or unavailable

## How this service works

Returns a 0-100 market-maker manipulation risk score for any token contract address, with breakdown metrics covering volume authenticity, holder concentration, MM wallet signals, and price-versus-liquidity analysis. Supports multiple EVM and Solana chains.

## Output

A JSON object containing a 0-100 market-maker manipulation risk score for the queried token, along with breakdown metrics: volume authenticity assessment, holder concentration signals, identified MM wallet activity, and price-versus-liquidity analysis. Higher scores indicate greater manipulation risk.
