Pig Docs

Pig is an API to launch and automate Windows apps. Plug this SDK into your AI Agent apps to give them a computer!

Warning: This API and associated infrastructure are currently in alpha and will likely undergo changes.

Installation

Install the package using pip:

pip install pig-python

This installation includes both the Python SDK and the pig command-line interface.

Quick Start Guide

Authentication

Set up your API key before using the SDK:

export PIG_SECRET_KEY=your_api_key

Apply Here to get your API key.

Basic Usage

Here's a simple example to launch and interact with a VM:

from pig import VM

# Create and connect to a new VM
vm = VM()
print("Starting VM...")
conn = vm.connect()  # Initial boot takes a few minutes

# Interact with the VM
conn.mouse_move(100, 100)  
conn.left_click(100, 100)  
conn.type("Hello, World!")

Resuming an Existing Session

To reconnect to an existing VM:

vm = VM(id="VM-ABCDEFG-ABCDEFG-ABCDEFG")
conn = vm.connect()
conn.type("Hello Again!")

Hint: if you don't know the VM ID, you can use the pig ls CLI command to list all VMs.

Resource Management

Always clean up your VMs when finished:

# Option 1: Stop VM (persists to disk)
vm.stop()

# Option 2: Terminate VM (deletes the disk)
vm.terminate()

For automated scripts, use the context manager pattern:

with VM().session() as conn:
    conn.mouse_move(100, 100)
    conn.left_click(100, 100)
    # VM automatically stops when the block exits

The context manager ensures your VMs stop.

Warning: During the alpha period, VMs left running without activity may be manually stopped by the Pig team. But please be a good citizen and clean up after yourself.

Command Line Interface

The pig CLI provides convenient VM management commands:

# List all VMs
pig ls

# Output format:
ID                          Status    Created
--------------------------  --------  ----------------
VM-6F25BH9-VHENR80-05CRX4Z  Running   2025-01-16 06:47
VM-6F228MS-Q0EEQR0-02JT39X  Running   2025-01-15 23:45

Available Commands:

• pig ls: List all VMs
• pig create: Create a new VM
• pig start <vm_id>: Start a specific VM
• pig stop <vm_id>: Stop a specific VM
• pig terminate <vm_id>: Terminate and delete a VM

API Reference

VM Class

The VM class is your interface for managing VMs, the cloud machines that run the Windows OS.

Constructor

VM(
    id: Optional[str] = None,           # Optionally attach to existing VM.
                                        # If none, new VM will be created.

    image: Optional[Windows] = None,    # OS image configuration
    temporary: bool = False,            # If True, terminates VM after session
    api_key: Optional[str] = None       # API key (alternative to env var)
)

Methods

• create() -> str: Creates a new VM and returns its ID
• connect() -> Connection: Connects to the VM, creating if necessary
• session() -> VMSession: Creates a managed VM session
• start(): Starts the VM
• stop(): Stops the VM
• terminate(): Terminates and deletes the VM

Tip: During development and exploration, prefer using the imperative API (vm.start(), vm.stop()) so you can watch the VM and experiment. Use the context manager (vm.session()) once you're ready to automate tasks.

Connection Class

The connection class is your interface for interracting with a running VM. This is what you'll expose as Tools to your agent.

A Connection has the following methods:

Mouse Operations

• cursor_position() -> Tuple[int, int]: Get current cursor position
• mouse_move(x: int, y: int): Move cursor to coordinates
• left_click(x: Optional[int], y: Optional[int]): Left click at current location, or at specified coordinates
• left_click_drag(x: int, y: int): Click and drag from current location to target coordinates
• double_click(x: Optional[int], y: Optional[int]): Double click at current location, or at specified coordinates
• right_click(x: Optional[int], y: Optional[int]): Right click at current location, or at specified coordinates

Keyboard Operations

• type(text: str): Type text into VM. Maps to keystrokes, executed with a short delay between each character.
• key(combo: str): Send key combination (e.g., 'ctrl+c', 'alt+Tab'). Supports multiple key strokes separated by space (e.g., 'shift-h i ctrl+a ctrl+c')

Screen Operations

• screenshot() -> bytes: Capture screenshot (BMP format)
• width -> int: Get VM width (1024)
• height -> int: Get VM height (768)

Control Management

• yield_control(): Transfer control to human operator. This makes all future interactions error until a button is clicked in the UI to grant control back to the agent.
• await_control(): Wait for control to be returned to the agent.

Windows Class

Configures Windows VM images.

Windows(version: str = "2025")
    .install(application: str) -> Windows  # Chain multiple installations

Advanced Usage

Custom Image Configuration

img = (
    Windows(version="2025")
    .install("Office") # Office is currently the only supported application.
)

vm = VM(image=img)
vm.create()

Temporary VM Sessions

vm = VM(temporary=True)
with vm.session() as conn:
    # VM terminates after block exit, rather than stopping.
    # This deletes the VM disk, making it no longer usable.

Configuration
