Web Unlocker

The Web Unlocker lets you retrieve fully-rendered page content from any URL without managing a browser session. It handles residential proxies, captcha solving, and fingerprinting automatically — so bot-protected sites respond as if you’re a real user.

Quick Start

import AnchorBrowser from 'anchorbrowser';

const anchorClient = new AnchorBrowser({ apiKey: process.env.ANCHOR_API_KEY });

const content = await anchorClient.tools.fetchWebpage({
  url: 'https://www.g2.com/products/notion/reviews',
});

console.log(content);

import os
from anchorbrowser import Anchorbrowser

anchor_client = Anchorbrowser(api_key=os.getenv('ANCHOR_API_KEY'))

content = anchor_client.tools.fetch_webpage(
    url='https://www.g2.com/products/notion/reviews',
)

print(content)

Examples

Scrape a protected site

import AnchorBrowser from 'anchorbrowser';

const anchorClient = new AnchorBrowser({ apiKey: process.env.ANCHOR_API_KEY });

const content = await anchorClient.tools.fetchWebpage({
  url: 'https://www.indeed.com/jobs?q=software+engineer&l=New+York',
});

console.log(content);

import os
from anchorbrowser import Anchorbrowser

anchor_client = Anchorbrowser(api_key=os.getenv('ANCHOR_API_KEY'))

content = anchor_client.tools.fetch_webpage(
    url='https://www.indeed.com/jobs?q=software+engineer&l=New+York',
)

print(content)

Fetch multiple pages in parallel

import AnchorBrowser from 'anchorbrowser';

const anchorClient = new AnchorBrowser({ apiKey: process.env.ANCHOR_API_KEY });

const urls = [
  'https://www.crunchbase.com/organization/openai',
  'https://www.crunchbase.com/organization/anthropic',
  'https://www.crunchbase.com/organization/mistral-ai',
];

const pages = await Promise.all(
  urls.map((url) => anchorClient.tools.fetchWebpage({ url })),
);

pages.forEach((content, index) => {
  console.log(urls[index], content.slice(0, 200));
});

import os
from anchorbrowser import Anchorbrowser

anchor_client = Anchorbrowser(api_key=os.getenv('ANCHOR_API_KEY'))

urls = [
    'https://www.crunchbase.com/organization/openai',
    'https://www.crunchbase.com/organization/anthropic',
    'https://www.crunchbase.com/organization/mistral-ai',
]

for url in urls:
    content = anchor_client.tools.fetch_webpage(url=url)
    print(url, content[:200])

When given a PDF URL, the Web Unlocker returns the file directly as a binary response. To extract text content from a PDF instead, use the Get webpage content tool — it handles PDF pages the same as any other page.

Web Unlocker vs. Browser Sessions

	Web Unlocker	Browser Session
Setup	No session needed	Create a session first
Stealth	Always on	Configurable
Speed	No cold start	Session startup time
Best for	High-volume scraping, one-shot fetches	Multi-step workflows, interactive automation

Use the Web Unlocker when you need content from a single URL. Use a browser session when you need to navigate, click, fill forms, or maintain state across multiple pages.
