---

🚀 Quick Start

Installation

# Install the package
pip install intelliscraper-core

# Install Playwright browser (Chromium)
playwright install chromium

[!NOTE] Playwright requires browser binaries installed separately. The command above installs Chromium.

⚡ Basic Scraping

import asyncio
from intelliscraper import AsyncScraper, ScrapStatus

async def main():
    async with AsyncScraper() as scraper:
        response = await scraper.scrape("https://example.com")

        if response.status == ScrapStatus.SUCCESS:
            print(f"HTTP {response.http_status_code}")
            print(f"Time: {response.elapsed_time:.2f}s")
            print(response.scrap_html_content[:500])

asyncio.run(main())

---

📦 Batch Scraping with Rate Limiting

Scrape many URLs with automatic rate limiting and concurrency control:

import asyncio
from intelliscraper import AsyncScraper, ScrapStatus

async def main():
    async with AsyncScraper(
        max_concurrent_pages=4,
        max_requests_per_minute=900,  # 15 requests/sec across all pages
    ) as scraper:
        urls = [f"https://example.com/page/{i}" for i in range(100)]
        results = await scraper.batch_scrape(urls)

        for result in results:
            print(
                f"{result.scrape_request.url} → "
                f"{result.status.value} "
                f"(HTTP {result.http_status_code}, "
                f"{result.elapsed_time:.2f}s)"
            )

asyncio.run(main())

[!IMPORTANT] The rate limit is shared across all concurrent pages. With max_concurrent_pages=4 and max_requests_per_minute=900, the 4 pages share a combined budget of 15 requests/second not 15/sec each.

---

🖥️ Local Browser Mode (CDP)

Connect to your running Chrome instance to reuse existing logins (LinkedIn, Gmail, etc.).

Setup (one-time)

# 1. Create the debug profile
make chrome-debug-profile

# 2. Open Chrome with the debug profile and log into your target sites
make chrome-debug-login URL=https://www.linkedin.com

# 3. Log in to the site in the browser that opens
# 4. Close Chrome when done

[!WARNING] The debug profile (~/.config/google-chrome-debug) is separate from your default Chrome profile. You must log into target sites in this profile before scraping.

Usage

import asyncio
from intelliscraper import AsyncScraper, ScrapStatus

async def main():
    async with AsyncScraper(
        use_local_browser=True,
        headless=False,
    ) as scraper:
        response = await scraper.scrape(
            "https://www.linkedin.com/jobs/collections/recommended/"
        )

        if response.status == ScrapStatus.SUCCESS:
            print(f"HTTP {response.http_status_code}")
            print(f"Session: {response.session_id}")
            print(f"Mode: {response.browser_mode}")

asyncio.run(main())

How It Works

1. IntelliScraper checks if Chrome is running with --remote-debugging-port=9222.
2. If not, it auto-launches Chrome using the debug profile.
3. Connects via CDP and reuses the existing browser context (all cookies and logins preserved).
4. Only the pages opened by IntelliScraper are closed on exit your Chrome session stays running.

---

🔐 Session-Based Scraping (Managed Browser)

For sites that require authentication without using your local Chrome:

1. Capture a Session

intelliscraper-session \
    --url "https://example.com" \
    --site "example" \
    --output "./example_session.json"

This opens a browser log in, then press Enter. Session data (cookies, localStorage, fingerprint) is saved to JSON.

2. Use the Session

import asyncio
import json
from intelliscraper import AsyncScraper, Session, ScrapStatus

async def main():
    with open("example_session.json") as f:
        session = Session(**json.load(f))

    async with AsyncScraper(session_data=session) as scraper:
        response = await scraper.scrape("https://example.com/dashboard")

        if response.status == ScrapStatus.SUCCESS:
            print(f"Session: {response.session_id}")
            print(response.scrap_html_content[:500])

asyncio.run(main())

---

📝 HTML Parsing

Default Parser

from intelliscraper.parsers import HTMLParser

parser = HTMLParser(url="https://example.com", html=html_content)
print(parser.text)               # Plain text
print(parser.links)              # List of absolute URLs
print(parser.navigable_links)    # Classified internal/external links
print(parser.markdown)           # Full Markdown
print(parser.markdown_for_llm)   # Cleaned Markdown (for LLM input)

Custom Parsers

Extend HTMLParser for site-specific extraction:

from functools import cached_property
from intelliscraper.parsers import HTMLParser

class MyJobParser(HTMLParser):
    """Custom parser for a job listing site."""

    @cached_property
    def job_title(self) -> str | None:
        tag = self.soup.select_one("h1.job-title")
        return tag.get_text(strip=True) if tag else None

    @cached_property
    def company(self) -> str | None:
        tag = self.soup.select_one("span.company-name")
        return tag.get_text(strip=True) if tag else None

---

🌐 Proxy Support

Proxy is used in managed browser mode only (not with local browser / CDP).

Bright Data Proxy

import asyncio
from intelliscraper import AsyncScraper, BrightDataProxy, ScrapStatus

async def main():
    proxy = BrightDataProxy(
        host="brd.superproxy.io",
        port=22225,
        username="your-username",
        password="your-password",
    )

    async with AsyncScraper(proxy=proxy) as scraper:
        response = await scraper.scrape("https://example.com")
        print(f"Status: {response.status.value}")

asyncio.run(main())

Custom Proxy Provider

from intelliscraper import ProxyProvider, Proxy

class MyProxy(ProxyProvider):
    def get_proxy(self) -> Proxy:
        return Proxy(
            server="http://my-proxy.com:8080",
            username="user",
            password="pass",
        )

[!NOTE] All pages within a single AsyncScraper instance share the same proxy. For different proxies, create separate AsyncScraper instances.

---

📊 Response Model

Every scrape() and batch_scrape() call returns a ScrapeResponse with:

Field	Type	Description
scrape_request	ScrapeRequest	Original request parameters
status	ScrapStatus	Outcome: SUCCESS, PARTIAL_SUCCESS, FAILED, RATE_LIMITED, BLOCKED, TIMEOUT
http_status_code	int | None	Actual HTTP status from the server (200, 403, 429, etc.)
elapsed_time	float | None	Total scrape duration in seconds
scrap_html_content	str | None	Raw HTML from the page
error_msg	str | None	Error message on failure
session_id	str | None	Session site identifier used
browser_mode	str | None	"local_browser" or "managed_browser"
