📦 Quickstart: Developer Integrations

1. ElizaOS Autonomous Agent Plugin

Install from the global npm registry:

npm install @kurox_real/plugin-rugshield-402

Register in your agent character definition:

import { rugshieldPlugin } from "@kurox_real/plugin-rugshield-402";

export const character = {
  name: "AutonomousDeFiTrader",
  plugins: [rugshieldPlugin],
  // ... rest of character config
};

When your agent evaluates a swap, it triggers the PRE_SWAP_RISK_CHECK action automatically.

---

2. Coinbase AgentKit (LangChain / Python / TS)

Install the provider:

npm install @kurox_real/agentkit-rugshield-402

Initialize with AgentKit:

import { rugshieldActionProvider } from "@kurox_real/agentkit-rugshield-402";
import { AgentKit } from "@coinbase/agentkit";

const agentKit = await AgentKit.from({
  actionProviders: [rugshieldActionProvider()],
});

---

3. Direct HTTP API (cURL / Any Language)

curl -X POST https://rugshield-402.onrender.com/v1/scan \
  -H "Content-Type: application/json" \
  -d '{
    "token_address": "0x4200000000000000000000000000000000000006",
    "chain_id": 8453,
    "simulate_sell": true
  }'

---

4. Python / Quantitative Bot Wrapper

import requests

def scan_token(token_address: str):
    url = "https://rugshield-402.onrender.com/v1/scan"
    res = requests.post(url, json={
        "token_address": token_address,
        "chain_id": 8453,
        "simulate_sell": True
    })
    
    if res.status_code == 402:
        payment_info = res.json()
        print("x402 Payment Challenge:", payment_info)
        # Agent signs and includes payment permit
    return res.json()
