# Augur

> EVM smart contract risk scoring API. Analyzes bytecode for 8 risk patterns and returns a 0-100 score. Pay $0.10/call via x402 in USDC on Base. No API key needed.

## What It Does

Augur fetches on-chain bytecode for any EVM smart contract on Base (EIP-155:8453) and runs 8 detectors to produce a composite risk score from 0 (safe) to 100 (critical).

## How to Call

```
GET https://augurrisk.com/analyze?address=0xC02aaA39b223FE8D0A0e5C4F27eAD9083C756Cc2
```

Payment: Include a `PAYMENT-SIGNATURE` header with an x402 payment proof ($0.10 USDC on Base). Any x402-compatible HTTP client handles this automatically.

## Example Response

```json
{
  "address": "0xC02aaA39b223FE8D0A0e5C4F27eAD9083C756Cc2",
  "score": 0,
  "level": "safe",
  "bytecode_size": 2846,
  "findings": [],
  "category_scores": {}
}
```

## Risk Levels

- **safe** (0-15): No significant risks detected
- **low** (16-35): Minor concerns, generally safe
- **medium** (36-55): Notable risks, review before interacting
- **high** (56-75): Significant risks detected
- **critical** (76-100): Severe risks, avoid interaction
