API Farm

A shared API key pool server and client for managing and using API keys efficiently. This package supports both command-line interface (CLI) and programmatic (SDK) usage.

Features

• Shared API Key Pool: Centralize API keys for multiple users
• User Management: Register, login, and manage API keys per user
• Dual Interface: Use via CLI commands or Python SDK
• Load Balancing: Automatic rotation across available API keys
• Easy Installation: Pip-installable package

Installation

From Source (Development)

# Clone the repository
git clone <your-repo-url>
cd api_farm

# Install in development mode
pip install -e .

From PyPI (When Published)

pip install api-farm

Quick Start

1. Start the Server

# Start the server (prints IP address for client connection)
api-farm-server

# Or with custom host/port
api-farm-server --host 0.0.0.0 --port 8081

The server will display connection information:

============================================================
API Farm Server Starting...
============================================================
Server running on:
  - Local:   http://localhost:8081
  - Network: http://192.168.1.100:8081

To connect clients, set the environment variable:
  export API_FARM_SERVER_URL=http://192.168.1.100:8081
============================================================

2. Configure Client Environment

Required: Set the server URL as an environment variable:

# Use the URL displayed by the server
export API_FARM_SERVER_URL=http://localhost:8081

3. Use the CLI

# Register a new user
api-farm register myuser mypassword

# Login
api-farm login myuser mypassword

# Add an API key
api-farm add-key "your-api-key-here"
# Import keys from a file
api-farm add-key --file api.json

# List your keys
api-farm list-keys

# Remove a key
api-farm remove-key "your-api-key-here"

# Logout
api-farm logout

Usage

Command Line Interface (CLI)

The CLI requires the API_FARM_SERVER_URL environment variable to be set.

Available Commands:

• python -m api_farm register <username> <password> - Register a new user
• python -m api_farm login <username> <password> - Login and save authentication token
• python -m api_farm logout - Logout and remove token
• python -m api_farm add-key <api_key> [--base-url <url>] - Add an API key to your pool
• python -m api_farm list-keys - List all your API keys
• python -m api_farm remove-key <api_key> - Remove an API key from your pool
• python -m api_farm chat "[{\"role\":\"user\", \"content\":\"Hello!\"}]" and it succeeded.
• python -m api_farm batch-chat -f batch_messages.json with a test file and it succeeded.

Server Commands:

• api-farm-server [--host HOST] [--port PORT] - Start the API Farm server

Python SDK

Import and use the client in your Python code:

from api_farm import APIPoolClient
import os

# Method 1: Use environment variable
os.environ['API_FARM_SERVER_URL'] = 'http://localhost:8081'
client = APIPoolClient()

# Method 2: Pass server URL explicitly
client = APIPoolClient(server_url='http://localhost:8081')

# Register a user
response = client.register('username', 'password')
print(response)

# Login
token = client.login('username', 'password')

# Add API key
client.add_key('your-api-key', base_url='https://integrate.api.nvidia.com/v1')

# Import keys from file
client.add_keys_from_file("api.json")

# List keys
keys = client.list_keys()
print(keys)

# Make a chat completion request (uses shared pool)
response = client.chat_completions(
    model='meta/llama-3.1-8b-instruct',
    messages=[{'role': 'user', 'content': 'Hello!'}],
    max_tokens=100
)
print(response)

# Remove a key
client.remove_key('your-api-key')

# Logout
client.logout()

Programmatic Server Usage

You can also start the server programmatically:

from api_farm.server import app
import uvicorn

# Start the server
uvicorn.run(app, host="0.0.0.0", port=8081)
