Handle SSL Certificate Warning + +Always suppress the SSL warning when using self-signed certificates: + +```python +import requests +import urllib3 + +# Disable SSL warnings (only for self-signed certs you trust) +urllib3.disable_warnings(urllib3.exceptions.InsecureRequestWarning) + +# Now requests with verify=False won't warn +response = requests.get("https://50.28.86.131/health", verify=False) +``` + +### 2. Rate Limiting + +Respect the API rate limits: + +```python +import time + +def rate_limited_request(endpoint, delay=0.1): + """Make request with rate limiting""" + response = requests.get( + f"{NODE_URL}{endpoint}", + verify=False + ) + time.sleep(delay) # Wait between requests + return response.json() + +# Safe: space out requests +for wallet in wallets: + data = rate_limited_request(f"/wallet/balance?miner_id={wallet}") + time.sleep(0.5) # 500ms between requests +``` + +### 3. Cache Results + +Avoid repeated API calls for the same data: + +```python +import time +from functools import wraps + +def cached(ttl=300): + """Cache decorator with TTL (in seconds)""" + def decorator(func): + cache = {} + last_update = [0] + + @wraps(func) + def wrapper(*args, **kwargs): + now = time.time() + if now - last_update[0] > ttl: + cache['result'] = func(*args, **kwargs) + last_update[0] = now + return cache['result'] + + return wrapper + return decorator + +@cached(ttl=60) +def get_epoch(): + """Get epoch info (cached for 60 seconds)""" + return requests.get(f"{NODE_URL}/epoch", verify=False).json() + +# Fast: uses cached result +for i in range(10): + epoch = get_epoch() # Only makes 1 API call +``` + +### 4. Validate Input + +Always validate user input: + +```python +import re + +def validate_wallet_name(wallet): + """Validate wallet name format""" + if not isinstance(wallet, str): + raise ValueError("Wallet must be a string") + + if len(wallet) < 3: + raise ValueError("Wallet name too short") + + if len(wallet) > 50: + raise ValueError("Wallet name too long") + + # Alphanumeric and hyphens only + if not re.match(r'^[a-zA-Z0-9_-]+$', wallet): + raise ValueError("Invalid wallet name characters") + + return wallet + +# Usage +try: + wallet = validate_wallet_name("my-wallet-123") + print(f"Valid: {wallet}") +except ValueError as e: + print(f"Invalid: {e}") +``` + +### 5. Log API Requests + +Track your API usage for debugging: + +```python +import logging +from datetime import datetime + +# Configure logging +logging.basicConfig( + filename='rustchain_api.log', + level=logging.INFO, + format='%(asctime)s - %(levelname)s - %(message)s' +) + +def logged_request(endpoint, params=None): + """Make request with logging""" + try: + response = requests.get( + f"{NODE_URL}{endpoint}", + params=params, + verify=False + ) + logging.info(f"GET {endpoint} -> {response.status_code}") + return response.json() + except Exception as e: + logging.error(f"GET {endpoint} failed: {e}") + raise + +# Usage +result = logged_request("/epoch") +``` + +### 6. Secure Wallet Operations + +Never hardcode wallet names or secrets: + +```python +import os +from dotenv import load_dotenv + +# Load from .env file +load_dotenv() + +WALLET = os.getenv("RUSTCHAIN_WALLET") +if not WALLET: + raise ValueError("Set RUSTCHAIN_WALLET environment variable") + +# Use wallet safely +balance = get_wallet_balance(WALLET) +``` + +Create `.env` file: +``` +RUSTCHAIN_WALLET=my-wallet-name +RUSTCHAIN_NODE=https://50.28.86.131 +``` + +--- + +## Troubleshooting + +### "SSL: CERTIFICATE_VERIFY_FAILED" + +**Solution:** Use `verify=False` (you've already trusted the self-signed cert): + +```python +response = requests.get("https://50.28.86.131/health", verify=False) +``` + +### "ConnectionError: Cannot connect" + +**Check:** +1.
