Browserless

Browserless Unblock & Stealth API

Bypass bot detection and anti-scraping measures. `/unblock` handles aggressive anti-bot challenges end-to-end. The stealth toggle (`/stealth`, `/chromium/stealth`, `/chrome/stealth`) randomizes browser fingerprints for longer-running automation.

OpenAPI Specification

browserless-unblock-stealth-api-openapi.yml Raw ↑ 
openapi: 3.2.0
info:
  title: Browserless Unblock & Stealth API
  version: 2.57.0
  description: 'This is the API reference for **Browserless Enterprise and Cloud** deployments. You''ll find endpoints for capturing screenshots and PDFs, scraping content, running custom browser functions, solving CAPTCHAs, bypassing bot detection with stealth browsing, managing authenticated browser profiles, and orchestrating crawls.


    The API includes REST endpoints (JSON in, JSON or binary out), WebSocket connections for direct CDP/Playwright/Puppeteer access, and CDP extensions that expose Browserless-specific commands like `liveURL`, `solveCaptcha`, and `reconnect`. For the open-source container API, see the GitHub repository.


    ## Just Getting Started?


    Check out the Quick Start guide to launch your first session, or explore the BrowserQL IDE for a GraphQL-based automation workflow.


    ## Base URL


    All API requests go to your deployment''s base URL. For Browserless Cloud:


    ```plaintext

    https://production-sfo.browserless.io

    ```


    Self-hosted Enterprise deployments use the host and port where the container is running (default `http://localhost:3000`).


    ## Authentication


    Include your API token as a query parameter on every request:


    ```plaintext

    https://production-sfo.browserless.io/chromium/content?token=YOUR_API_TOKEN

    ```


    Tokens are managed from the Account dashboard. Self-hosted deployments set the token via the `TOKEN` environment variable. See connection details for all authentication options.


    ## Changelog


    For release notes and version history, see the Enterprise Changelog.


    ## Software keys


    Self-hosted Enterprise deployments use time-limited software keys for offline licensing. No external connections or callbacks are required. Keys are cryptographically secure and can''t be reverse engineered. When a key expires, the container exits with a semantic error code.


    To use a software key, set the `KEY` environment variable when running the container:


    ```bash

    docker run -e KEY=your-generated-key browserless/enterprise

    ```'
