tzafon 2.3.3

The official Python library for the computer API

Tzafon Python SDK

Remote browser and desktop automation. Control browsers and desktops programmatically through a simple Python API.

Installation

pip install tzafon

Quick Start

from tzafon import Computer

client = Computer()  # Reads TZAFON_API_KEY from environment

# Create and control a browser instance
with client.create(kind="browser") as computer:
    computer.navigate("https://wikipedia.com")

    result = computer.screenshot()
    url = computer.get_screenshot_url(result)
    print(f"Screenshot: {url}")

    computer.click(100, 200)
    computer.type("Hello, world!")

    # Automatically terminates when exiting context

Set your API key:

export TZAFON_API_KEY="your-api-key"

Or use a .env file with python-dotenv.

Features

Session Management

• Context manager support for automatic cleanup
• Manual session control when needed
• Browser, desktop, and code environments

Browser Actions

• Navigation: navigate(url)
• Mouse: click(), double_click(), right_click(), drag()
• Keyboard: type(), hotkey()
• Viewport: scroll(), set_viewport()
• Capture: screenshot(), html()
• Debug: Execute shell commands with debug()

Type Safety

• Full type annotations for IDE autocomplete
• Pydantic models for responses
• TypedDict for request parameters
• Helper methods for result extraction

Examples

Browser Automation

with client.create(kind="browser") as computer:
    # Navigate and interact
    computer.navigate("https://github.com/login")
    computer.click(300, 400)
    computer.type("username")
    computer.hotkey("Control", "a")  # Select all

    # Capture state
    html_result = computer.html()
    html = computer.get_html_content(html_result)

    # Execute commands
    debug_result = computer.debug("ls -la")
    output = computer.get_debug_response(debug_result)

Manual Session Management

computer = client.create(kind="browser")
try:
    computer.navigate("https://example.com")
    screenshot = computer.screenshot()
finally:
    computer.terminate()

Async Support

from tzafon import AsyncComputer

async with AsyncComputer() as client:
    computer = await client.computers.create(kind="browser")
    await client.computers.navigate(computer.id, url="https://example.com")
    await client.computers.terminate(computer.id)

Advanced Usage

Raw SDK Access

The simplified wrapper uses the generated SDK under the hood. You can access it directly:

# Low-level API
response = client.computers.create(kind="browser")
client.computers.navigate(response.id, url="https://example.com")
result = client.computers.capture_screenshot(response.id)
client.computers.terminate(response.id)

Error Handling

import tzafon

try:
    with client.create(kind="browser") as computer:
        computer.navigate("https://example.com")
except tzafon.RateLimitError:
    print("Rate limit exceeded, back off")
except tzafon.AuthenticationError:
    print("Invalid API key")
except tzafon.APIError as e:
    print(f"API error: {e}")

Configuration

from tzafon import Computer

client = Computer(
    api_key="your-api-key",       # Or use TZAFON_API_KEY env var
    base_url="https://...",        # Optional: custom endpoint
    timeout=120.0,                 # Request timeout in seconds
    max_retries=2,                 # Retry failed requests
)
