Nstbrowser SDK for Python

A Python SDK for interacting with Nstbrowser API v2

Overview

This SDK implements Nstbrowser API v2, which is the recommended API with complete functionality from v1 plus additional features. It provides a comprehensive set of tools for managing browser profiles, controlling browser instances, managing local browser data, and utilizing Chrome DevTools Protocol (CDP) for browser automation.

The SDK enables you to:

• Create and manage browser profiles with detailed fingerprint configurations
• Start and stop browser instances individually or in batch
• Configure and manage proxies for profiles
• Manage profile tags for better organization
• Clear browser cache and cookies
• Connect to browsers using Chrome DevTools Protocol (CDP)
• Automate browser actions through CDP integration

Installation

pip install nstbrowser

Getting Started

To use the SDK, you need an API key from Nstbrowser:

from nstbrowser import NstbrowserClient

# Initialize the client with your API key
client = NstbrowserClient(api_key="your_api_key")

# Now you can use the various services
profile_id = "your_profile_id"

# Start a browser instance
response = client.browsers.start_browser(profile_id=profile_id)
print(f"Browser started: {response}")

# Stop the browser instance
response = client.browsers.stop_browser(profile_id=profile_id)
print(f"Browser stopped: {response}")

Available Services

The SDK provides the following services:

BrowsersService

Manages browser instances, including starting, stopping, and getting information about browsers.

# Start a browser for a specific profile
response = client.browsers.start_browser(profile_id="your_profile_id")

# Start multiple browsers in batch
response = client.browsers.start_browsers(profile_ids=["profile_id_1", "profile_id_2"])

# Start a once-off browser with custom configuration
config = {
    "name": "testProfile",
    "platform": "Windows",
    "kernelMilestone": "132",
    "headless": False,
    "proxy": "http://admin:123456@127.0.0.1:8000",
    "fingerprint": {
        "userAgent": "Mozilla/5.0 (Windows NT 10.0; Win64; x64) ...",
        "screen": {"width": 1280, "height": 1024}
    },
    "startupUrls": ["https://www.example.com"]
}
response = client.browsers.start_once_browser(data=config)

# Stop a browser
response = client.browsers.stop_browser(profile_id="your_profile_id")

# Stop multiple browsers
response = client.browsers.stop_browsers(profile_ids=["profile_id_1", "profile_id_2"])

# Get active browsers
response = client.browsers.get_browsers(status="running")

# Get browser pages
response = client.browsers.get_browser_pages(profile_id="your_profile_id")

# Get browser debugger information
response = client.browsers.get_browser_debugger(profile_id="your_profile_id")

ProfilesService

Manages browser profiles, including creation, deletion, proxy configuration, and tag management.

# Create a new profile
profile_data = {
    "name": "New Profile",
    "platform": "Windows",
    "kernelMilestone": "132",
    "fingerprint": {
        "userAgent": "Mozilla/5.0 (Windows NT 10.0; Win64; x64) ...",
        "timezone": "Asia/Hong_Kong"
    }
}
response = client.profiles.create_profile(data=profile_data)

# Get profiles with filtering
response = client.profiles.get_profiles(data={"page": 1, "pageSize": 10})

# Delete a profile
response = client.profiles.delete_profile(profile_id="your_profile_id")

# Delete multiple profiles
response = client.profiles.delete_profiles(profile_ids=["profile_id_1", "profile_id_2"])

# Update a profile's proxy
response = client.profiles.update_profile_proxy(profile_id="your_profile_id", data={"url": "http://admin:654321@127.0.0.1:8000"})

# Reset a profile's proxy
response = client.profiles.reset_profile_proxy(profile_id="your_profile_id")

# Manage profile tags
response = client.profiles.create_profile_tags(profile_id="your_profile_id", data=[{"name": "social", "color": "#646AEE"}])
response = client.profiles.get_profile_tags()

LocalsService

Manages local browser data, such as cache and cookies.

# Clear browser cache
response = client.locals.clear_profile_cache(profile_id="your_profile_id")

# Clear browser cookies
response = client.locals.clear_profile_cookies(profile_id="your_profile_id")

CdpEndpointsService

Provides connections to browsers using Chrome DevTools Protocol (CDP) for automation.

# Connect to a browser using CDP
config = {
    "headless": False,
    "autoClose": False
}
response = client.cdp_endpoints.connect_browser(profile_id="your_profile_id", config=config)

# Connect to a once-off browser using CDP
config = {
    "name": "testProfile",
    "platform": "Windows",
    "kernelMilestone": "132",
    "autoClose": False,
    "headless": False
}
response = client.cdp_endpoints.connect_once_browser(config=config)

CDP Integration with Playwright

One powerful feature is the ability to connect to browsers using Chrome DevTools Protocol (CDP) and automate them with Playwright:

# Get the CDP WebSocket URL
websocket_url = client.cdp_endpoints.connect_browser(
    profile_id="your_profile_id", 
    config={"headless": False}
)["data"]["webSocketDebuggerUrl"]

# Use the URL with Playwright for automation
from playwright.async_api import async_playwright

async def automate():
    async with async_playwright() as p:
        browser = await p.chromium.connect_over_cdp(websocket_url)
        page = browser.contexts[0].pages[0]
        await page.goto("https://example.com")
        # ... perform other actions

Complete examples for CDP automation are available in the examples/cdp_endpoints directory.
