apirotater 0.5.0

Python library for API key rotation, rate limit control and load balancing

APIRotater

A simple Python library that automatically manages and rotates multiple API keys to prevent rate limit issues.

What It Does

• Automatically rotates between multiple API keys so you don't hit rate limits
• Tracks usage of each API key
• Manages rate limits by specifying max uses in a time window
• Loads API keys from .env files in current directory, parent directory, or executable location
• Works with Windows EXE applications when packaged

Installation

pip install apirotater

Quick Start

1. Create a .env file with your API keys

API_KEY_1=your_first_api_key
API_KEY_2=your_second_api_key
API_KEY_3=your_third_api_key

2. Use in your code

import apirotater

# Get an API key
api_key = apirotater.key()

# Use the API key for your request
response = make_your_api_request(api_key)

# IMPORTANT: Always report when you've used a key
apirotater.hit(api_key)

Basic Example

import apirotater
import time

# Simple usage loop
for _ in range(10):
    # Get a new API key (rotates automatically)
    api_key = apirotater.key()
    
    # Use the key for your API request
    print(f"Making request with key: {api_key}")
    
    # IMPORTANT: Report that you used the key
    apirotater.hit(api_key)
    
    # Wait before next request
    time.sleep(1)

Rate Limiting

import apirotater

# Get a key with maximum 5 uses in 60 seconds
api_key = apirotater.key(time_window=60, max_uses=5)

# Use the key
print(f"Using key: {api_key}")

# Report usage
apirotater.hit(api_key)

Custom .env File Location

For Windows EXE applications or custom setups, you can specify the .env file location:

import apirotater
import os
import sys

# For regular applications - use current directory
env_path = os.path.join(os.getcwd(), ".env")

# For Windows EXE applications - use executable directory
# env_path = os.path.dirname(os.path.abspath(sys.argv[0]))

# Load API keys from specific location
apirotater.load_env_file(env_path)

# Then use normally
api_key = apirotater.key()

API Reference

• key(time_window=60, max_uses=100) - Get an API key
• hit(api_key) - Report that you've used an API key (ALWAYS call this)
• load_env_file(path) - Load API keys from a specific .env file
• usage() - Get usage statistics for all keys
• get_all_keys() - Get a list of all loaded API keys
• get_current_key_name() - Get the name of the current API key

Error Handling

import apirotater
import time

try:
    api_key = apirotater.key()
    # Use the key...
    apirotater.hit(api_key)
except apirotater.RateLimitExceeded:
    # All keys exceeded rate limits
    print("All API keys reached rate limit")
    time.sleep(60)  # Wait and try again
