Web Unlocker is a universal scraping API. Send any URL, get back fully rendered HTML or the page as Markdown or JSON — no infrastructure to manage, no blocks, no failed requests. It works as a complete replacement for your scraping stack: browser automation, proxy management, fingerprinting, CAPTCHA solving — all handled in a single API call. Whether you’re scraping a simple static page or a heavily protected JavaScript-rendered site, the same endpoint handles it.

​
What it solves

Modern websites are hard to scrape. A plain curl or requests call often returns a challenge page, a blank response, or broken HTML because the content is loaded by JavaScript. Web Unlocker handles all of this automatically:
  • JavaScript rendering — pages are loaded in a real browser and fully executed before content is captured
  • Anti-bot bypass — Cloudflare, DataDome, PerimeterX and similar protections are handled automatically
  • Smart IP rotation — requests are routed through clean residential IPs with realistic browser fingerprints
  • CAPTCHA solving — common CAPTCHA challenges are resolved without manual intervention
  • Price tier targeting — routes requests through the appropriate proxy tier for the target site

​
What you get back

A successful request returns the page in one format. Choose it with the format query parameter:

​
Pricing

Web Unlocker uses success-based billing — you are only charged when the request succeeds. Failed attempts are free. Pricing scales with volume: For custom volume pricing, contact webunlocker@gologin.com.

Web Unlocker vs. self-managed proxies

Running your own proxy infrastructure is expensive and fragile. Web Unlocker handles everything as a managed service:

​
Common use cases

  • Price monitoring — scrape e-commerce sites that block automated requests
  • Lead generation — extract contact data from directories and business listings
  • Market research — collect product data, reviews, or job listings at scale
  • Content aggregation — build news or data feeds from sites without an API
  • AI pipelines — feed rendered HTML into LLMs for extraction or summarization

​
How it works

Web Unlocker runs a real Chromium browser in the cloud for each task. When you send a URL:
  1. A browser is launched with a residential IP and realistic browser fingerprint
  2. The page is navigated, JavaScript is executed, and dynamic content is loaded
  3. Anti-bot challenges and CAPTCHAs are handled automatically
  4. The rendered HTML is returned, or Markdown or JSON if you ask for it with format
You never manage infrastructure. There are no browsers to spin up, no proxy lists to maintain, and no bypass logic to build. Web Unlocker effectively replaces an entire scraping stack — browser automation framework, proxy provider, anti-bot solution — with a single HTTP request.

​
How to use it

Send a GET request with the target URL as a query parameter. The response is the fully rendered HTML.
To get Markdown or JSON instead, add format=markdown or format=json to the query. See the Quickstart for examples in Python and JavaScript and for error codes, or Use Cases for common integration patterns.

​
CLI and SDK

In addition to the raw HTTP API, Gologin provides higher-level tools for working with Web Unlocker:
  • Web Unlocker SDK and CLI — minimal TypeScript SDK (gologin-webunlocker) with typed methods and a CLI for quick scraping
  • Gologin Web Access CLI — unified CLI that combines Web Unlocker with Cloud Browser, adding batch scraping, crawling, search, change tracking, and structured extraction
  • AI Skills — plug-and-play skills for Claude Code agents

Get access

To get an API key, fill in the form on the Web Unlocker page. You get the key within one business day, along with free requests to test on your own targets. No card is needed.
