Rugcheck.xyz is a specialized security platform that analyzes cryptocurrency tokens and smart contracts for signs of malicious behavior or inherent risk. It inspects:

Contract code for vulnerabilities or honeypot tactics
Liquidity and lock status
Tokenomics and tax structures
Developer and owner wallets
Holder distribution
And more

The Rugcheck.xyz API allows you to:

Automate risk analysis in your trading bots or dashboards
Scale due diligence across thousands of tokens

This is invaluable for engineering teams building DeFi tools, crypto exchanges, or wallet integrations.

Getting Started: Obtain and Secure Your Rugcheck.xyz API Key

Before making API calls, you need an API key:

Register/Login: Create an account at Rugcheck.xyz.
Find API Settings: Look for "API" or "Developer" sections in your dashboard.
Generate Key: Create a new API key and name it for tracking.
Secure the Key: Store it in a password manager or as an environment variable—never commit it to public code or client-side apps.

All API requests require the key in the X-API-KEY header.

Base URL:
https://api.rugcheck.xyz

Reference:
See the Swagger documentation for a full endpoint list: https://api.rugcheck.xyz/swagger/index.html

Core API Endpoints for Crypto Risk Analysis

Some of the most useful endpoints for developers include:

GET /tokens/scan/{chain}/{contractAddress} — Real-time token security scan
GET /tokens/source-code/{chain}/{contractAddress} — Fetch verified contract source code and ABI
GET /wallets/risk-rating/{chain}/{walletAddress} — Assess wallet risk profile
GET /tokens/search — Search tokens by name or symbol

Python Integration: Practical Rugcheck.xyz API Examples

The following Python snippets will help you quickly integrate Rugcheck.xyz API into your workflow. These examples assume:

Python 3.x is installed
The requests library is available (pip install requests)
Your API key is set in the environment variable RUGCHECK_API_KEY

1. Setup: Secure API Key and Request Function

Store your API key securely as an environment variable. Here’s a reusable function for GET requests:

import requests
import json
import os

API_KEY = os.getenv('RUGCHECK_API_KEY')
BASE_URL = "https://api.rugcheck.xyz"

HEADERS = {
    "X-API-KEY": API_KEY,
    "Accept": "application/json"
}

def make_api_request(endpoint, params=None):
    if not API_KEY:
        print("Error: RUGCHECK_API_KEY environment variable not set.")
        return None

    url = f"{BASE_URL}{endpoint}"
    try:
        response = requests.get(url, headers=HEADERS, params=params, timeout=30)
        response.raise_for_status()
        return response.json()
    except requests.exceptions.HTTPError as http_err:
        print(f"HTTP error: {http_err}, Status: {response.status_code}")
        try:
            print(f"API Error Response: {response.json()}")
        except json.JSONDecodeError:
            print(f"API Error Response: {response.text}")
    except Exception as err:
        print(f"Request error: {err}")
    return None

2. Scan a Token for Security Risks

Scan any token on a supported chain and review its risk profile.

def get_token_scan_details(chain, contract_address, include_dex=True, include_events=False):
    endpoint = f"/tokens/scan/{chain}/{contract_address}"
    params = {
        "includeDexScreenerData": str(include_dex).lower(),
        "includeSignificantEvents": str(include_events).lower()
    }
    data = make_api_request(endpoint, params=params)
    if not data:
        print("Failed to retrieve token scan details.")
        return

    print(f"Risk Level: {data.get('riskLevel')}")
    print(f"Trust Score: {data.get('trustScore', {}).get('value')}")
    scams = data.get('scams', [])
    if scams:
        print("Scams Detected:")
        for scam in scams:
            print(f"  - {scam.get('type')}: {scam.get('message')}")
    else:
        print("No scams detected.")

    # Review warnings, liquidity, holders, taxes, etc.
    # ... (see original snippet for full details)

Usage Example:

# get_token_scan_details('bsc', '0xbb4CdB9CBd36B01bD1cBaEBF2De08d9173bc095c')

Interpretation Tips:

riskLevel "HIGH" or "CRITICAL" = proceed with caution
Unlocked liquidity, high or modifiable taxes, or suspicious owner wallets signal major risk

3. Retrieve Verified Contract Source Code

Check if a contract is verified and fetch its source code and ABI.

def get_token_source_code(chain, contract_address):
    endpoint = f"/tokens/source-code/{chain}/{contract_address}"
    data = make_api_request(endpoint)
    if not data:
        print("Failed to retrieve source code.")
        return

    print(f"Contract Name: {data.get('contractName')}")
    print(f"Is Verified: {data.get('isVerified')}")
    if data.get('isVerified'):
        source_code = data.get('sourceCode')
        if isinstance(source_code, str):
            print(f"Source Code Snippet:\n{source_code[:500]}")

Usage Example:

# get_token_source_code('ethereum', '0xA0b86991c6218b36c1d19D4a2e9Eb0cE3606eB48')

4. Assess a Wallet's Risk Profile

Reveal whether a wallet (such as a deployer or owner) is linked to risky projects.

def get_wallet_risk_rating(chain, wallet_address):
    endpoint = f"/wallets/risk-rating/{chain}/{wallet_address}"
    data = make_api_request(endpoint)
    if not data:
        print("Failed to retrieve wallet risk rating.")
        return

    print(f"Wallet Risk: {data.get('riskLevel')}")
    for token in data.get('associatedTokens', []):
        print(f"  Token: {token.get('symbol')} ({token.get('contractAddress')}) - Risk: {token.get('riskLevel')}")

Usage Example:

# get_wallet_risk_rating('bsc', '0x000000000000000000000000000000000000dead')

5. Search for Tokens by Name or Symbol

Find contract addresses and risk details for any token.

def search_for_token(query, chain=None, page_size=5):
    endpoint = "/tokens/search"
    params = {"query": query, "pageSize": page_size}
    if chain:
        params["chain"] = chain

    data = make_api_request(endpoint, params=params)
    if not data or 'items' not in data:
        print("No tokens found.")
        return

    for token in data['items']:
        print(f"{token.get('name')} ({token.get('symbol')}): {token.get('contractAddress')} [{token.get('chain')}] Risk: {token.get('riskLevel')}")

Usage Example:

# search_for_token("CAKE", chain="bsc")

6. List All Supported Blockchains

Quickly see which networks you can scan.

def list_supported_chains():
    endpoint = "/utils/chains"
    data = make_api_request(endpoint)
    if not data:
        print("Failed to retrieve chains.")
        return

    for chain in data:
        print(f"{chain.get('id')}: {chain.get('name')} ({chain.get('nativeCurrencySymbol')})")

Best Practices for Secure and Efficient Rugcheck.xyz API Integration

API Key Security: Always use environment variables; never hard-code your key.
Respect Rate Limits: Monitor for 429 Too Many Requests and back off as needed.
Error Handling: Expand the sample function to log and handle errors as appropriate for your stack.
Leverage Caching: Cache results like contract source code or scan data to avoid unnecessary API calls.
Combine With Manual Review: Automated analysis is powerful, but always supplement with your own research and judgment.
