Python 3.10+ Version License: AGPL v3 Code style: black

UltimaScraperAPI is a modular Python scraping framework designed to interact with premium content platforms such as OnlyFans, Fansly, and LoyalFans. It provides a unified, async-first API for authentication, user data retrieval, posts, messages, and media downloads with comprehensive session management and caching capabilities.

Platform Status:

  • ✅ OnlyFans: Fully supported and stable
  • 🚧 Fansly: Work in progress with limited functionality
  • 🚧 LoyalFans: Work in progress with limited functionality

uv pip install ultima-scraper-api

Using pip

pip install ultima-scraper-api

From Source

For development or the latest features:

# Clone the repository
git clone https://github.com/UltimaHoarder/UltimaScraperAPI.git
cd UltimaScraperAPI

# Install with uv
uv pip install -e .

# Or with pip
pip install -e .

💡 Quick Start

Basic Usage

import asyncio
from ultima_scraper_api import OnlyFansAPI, UltimaScraperAPIConfig

async def main():
    # Initialize configuration
    config = UltimaScraperAPIConfig()
    api = OnlyFansAPI(config)
    
    # Authentication credentials
    # Obtain these from your browser's Network tab (F12)
    # See: https://ultimahoarder.github.io/UltimaScraperAPI/user-guide/authentication/
    auth_json = {
        "cookie": "your_cookie_value",
        "user_agent": "your_user_agent",
        "x-bc": "your_x-bc_token"
    }
    
    # Use context manager for automatic cleanup
    async with api.login_context(auth_json) as authed:
        if authed and authed.is_authed():
            # Get authenticated user info
            me = await authed.get_me()
            print(f"Logged in as: {me.username}")
            
            # Get user profile
            user = await authed.get_user("username")
            if user:
                print(f"User: {user.username} ({user.name})")
                
                # Fetch user's posts
                posts = await user.get_posts(limit=10)
                print(f"Found {len(posts)} posts")
                
                # Download media from posts
                for post in posts:
                    if post.media:
                        for media in post.media:
                            print(f"Downloading: {media.filename}")
                            content = await media.download()
                            # Save content to file...

if __name__ == "__main__":
    asyncio.run(main())

Credential Extraction

You need three pieces of information from your browser:

  1. Cookie: Your session cookie
  2. User-Agent: Your browser's user agent string
  3. x-bc (OnlyFans only): Dynamic authorization token

Quick Steps:

  1. Open your browser and navigate to the platform
  2. Open Developer Tools (F12)
  3. Go to the Network tab
  4. Look for API requests and copy the required headers

For detailed instructions with screenshots, see the Authentication Guide.

Guest Mode (Limited Access)

Some platforms support guest access for public content:

async with api.login_context(guest=True) as authed:
    # Limited operations available (public profiles, posts, etc.)
    user = await authed.get_user("public_username")
    if user:
        print(f"Public profile: {user.username}")

🔧 Configuration

Basic Configuration

from ultima_scraper_api import UltimaScraperAPIConfig

# Load from JSON file
config = UltimaScraperAPIConfig.from_json_file("config.json")

# Or create programmatically
config = UltimaScraperAPIConfig()

Environment Variables

# Set up your credentials
export ONLYFANS_COOKIE="your_cookie_value"
export ONLYFANS_USER_AGENT="Mozilla/5.0 ..."
export ONLYFANS_XBC="your_x-bc_token"

Then load them in your code:

import os

auth_json = {
    "cookie": os.getenv("ONLYFANS_COOKIE"),
    "user_agent": os.getenv("ONLYFANS_USER_AGENT"),
    "x-bc": os.getenv("ONLYFANS_XBC")
}

Proxy Configuration

Configure HTTP, HTTPS, or SOCKS proxies:

from ultima_scraper_api import UltimaScraperAPIConfig
from ultima_scraper_api.config import Network, Proxy

config = UltimaScraperAPIConfig(
    network=Network(
        proxy=Proxy(
            http="http://proxy.example.com:8080",
            https="https://proxy.example.com:8080",
            # Or SOCKS proxy
            # http="socks5://proxy.example.com:1080"
        )
    )
)

Redis Configuration

Enable Redis for caching and session management:

from ultima_scraper_api.config import Redis

config = UltimaScraperAPIConfig(
    redis=Redis(
        host="localhost",
        port=6379,
        db=0,
        password="your_password"  # Optional
    )
)

For complete configuration options, see the Configuration Guide.

📖 Usage Examples

async with api.login_context(auth_json) as authed:
    # Get all active subscriptions
    subscriptions = await authed.get_subscriptions()
    
    for sub in subscriptions:
        user = sub.user
        print(f"{user.username} - Subscribed: {sub.subscribed_at}")
        print(f"  Expires: {sub.expires_at}")
        print(f"  Price: ${sub.price}")

Getting Messages

async with api.login_context(auth_json) as authed:
    # Get a specific user
    user = await authed.get_user("username")
    
    # Fetch message conversation
    messages = await user.get_messages(limit=50)
    
    for msg in messages:
        print(f"[{msg.created_at}] {msg.from_user.username}: {msg.text}")
        
        # Check for media attachments
        if msg.media:
            print(f"  Attachments: {len(msg.media)} media files")

Downloading Stories

import aiofiles

async with api.login_context(auth_json) as authed:
    user = await authed.get_user("username")
    
    # Get active stories
    stories = await user.get_stories()
    
    for story in stories:
        if story.media:
            for media in story.media:
                # Download media content
                content = await media.download()
                
                # Save to file
                filename = f"stories/{media.filename}"
                async with aiofiles.open(filename, "wb") as f:
                    await f.write(content)
                    
                print(f"Downloaded: {filename}")

Pagination and Batch Processing

async with api.login_context(auth_json) as authed:
    user = await authed.get_user("username")
    
    # Fetch all posts with pagination
    all_posts = []
    offset = 0
    limit = 50
    
    while True:
        posts = await user.get_posts(limit=limit, offset=offset)
        if not posts:
            break
            
        all_posts.extend(posts)
        offset += limit
        
        print(f"Fetched {len(all_posts)} posts so far...")
    
    print(f"Total posts: {len(all_posts)}")

Concurrent Operations

import asyncio

async with api.login_context(auth_json) as authed:
    # Get multiple users concurrently
    usernames = ["user1", "user2", "user3"]
    
    tasks = [authed.get_user(username) for username in usernames]
    users = await asyncio.gather(*tasks, return_exceptions=True)
    
    for username, user in zip(usernames, users):
        if isinstance(user, Exception):
            print(f"Error fetching {username}: {user}")
        else:
            print(f"Fetched: {user.username} - {user.posts_count} posts")
