# Clone the repository
git clone https://github.com/nathan0x-XYZ/alchemy-api-toolkit.git
cd alchemy-api-toolkit
# Install dependencies
pip install -r requirements.txt
# Set up your API key
cp .env.example .env
# Edit .env with your Alchemy API keyRetrieve ETH balance with automatic error handling:
from dotenv import load_dotenv
import os
import logging
from alchemy_api_debug import get_eth_balance
from validate_api_key import is_valid_alchemy_key
# Setup
load_dotenv()
api_key = os.getenv('ALCHEMY_API_KEY')
# Validate API key
if not is_valid_alchemy_key(api_key):
logging.error("Invalid API key format! Please check your .env file.")
exit(1)
# Get ETH balance
address = "0xd8dA6BF26964aF9D7eEd9e03E53415D37aA96045" # Vitalik's address
balance = get_eth_balance(address)
print(f"Balance: {balance} ETH")Use decorator pattern for retry logic:
from retry_with_backoff import retry_with_backoff
import requests
@retry_with_backoff(max_retries=3, base_delay=1, max_delay=30)
def fetch_data(url):
"""Fetch data with automatic retry on failure"""
response = requests.get(url, timeout=10)
response.raise_for_status()
return response.json()
# The function will automatically retry on failure
result = fetch_data("https://api.example.com/data")Process multiple requests in parallel with rate limiting:
from examples.batch_processing import process_addresses_in_parallel
# List of addresses to process
addresses = [
"0x71C7656EC7ab88b098defB751B7401B5f6d8976F",
"0xAb5801a7D398351b8bE11C439e05C5B3259aeC9B",
"0xBE0eB53F46cd790Cd13851d5EFf43D12404d33E8"
]
# Process in parallel with automatic rate limiting
results = process_addresses_in_parallel(addresses, batch_size=5)This toolkit follows a modular architecture designed for flexibility and maintainability:
┌─────────────────────────────────────────────────────────────┐

├───────────────┬───────────────┬───────────────┬─────────────┤
│ API Interface │ Reliability │ Data Process. │ Utility │
│ Layer │ Layer │ Layer │ Layer │

└───────────────┴───────────────┴───────────────┴─────────────┘
The toolkit is organized around these core components:
- API Interface Layer - Clean abstractions over Alchemy endpoints
- Reliability Layer - Rate limiting, retry logic, and error handling
- Data Processing Layer - Parsers and formatters for blockchain data
- Utility Layer - Helper functions and common operations
This layered approach ensures separation of concerns and makes the codebase easy to extend and maintain.
| Issue | Solution | Implementation |
|---|---|---|
| API Rate Limits | Adaptive rate limiting with queue management | RateLimiter class with configurable thresholds |
| Transient Network Failures | Exponential backoff with jitter | @retry_with_backoff decorator |
| Invalid API Responses | Comprehensive validation and error handling | Type checking and schema validation |
| IPFS Resolution Timeouts | Multi-gateway fallback strategy | Parallel gateway requests with timeout management |
| Inefficient Data Fetching | Batched and parallel processing | Async operations with worker pools |
The toolkit includes several optimizations for high-performance applications:
- Connection Pooling - Reuse HTTP connections for faster requests
- Caching Layer - Optional in-memory caching to reduce duplicate requests
- Parallel Processing - Process multiple requests concurrently
- Batch Operations - Combine multiple operations into single API calls
- Adaptive Timeouts - Dynamically adjust timeouts based on endpoint performance
