Sionix API Documentation

Real-time risk scoring, threat detection, and cluster intelligence across 7 EVM chains. Integrate in minutes. Powered by the Prism engine.

Overview

Sionix provides a REST API for detecting automated fraud, attacker clusters, and high-risk wallet activity on EVM-compatible chains. Every request returns a risk score, threat classification, and recommended action in milliseconds.

All responses follow a consistent format:

{
  "success": true,
  "data": { ... },
  "meta": {
    "requestId": "req_abc123",
    "version": "1.0.0"
  }
}

Quickstart

Get a risk score in under 60 seconds.

1. Get your API key

Sign up and include your key as x-api-key in every request.

2. Scan a wallet

curl -X POST https://api.sionix.tech/v1/wallet/scan \
  -H "Content-Type: application/json" \
  -H "x-api-key: YOUR_API_KEY" \
  -d '{"address": "0x742d35Cc6634C0532925a3b844Bc9e7595f2bD18", "chain": "ETH"}'

3. Response

{
  "success": true,
  "data": {
    "address": "0x742d35Cc6634C0532925a3b844Bc9e7595f2bD18",
    "chain": "ETH",
    "riskScore": 14,
    "riskTier": "LOW",
    "isMalicious": false,
    "threatType": "NONE",
    "recommendedAction": "none"
  }
}

Authentication

Every request requires an API key passed in the x-api-key header.

x-api-key: YOUR_API_KEY

API keys are tied to your account and plan tier. Keep them secret — keys are hashed on our side and cannot be recovered if lost.
