Visual CAPTCHA solving

Anchor browser solves CAPTCHA challenges using a vision-based approach, along with extension-based fallbacks. The vision-based approach imitates human behavior to solve any CAPTCHA (including Cloudflare) without multiple challenges.
CAPTCHA solving requires either an active proxy or a configured browser profile (the profile may carry its own egress IP and stable identity).
For the full list of available options, view the interactive api documentation

​
Enable CAPTCHA solving

import Anchorbrowser from 'anchorbrowser';

(async () => {
  const anchorClient = new Anchorbrowser({apiKey: process.env.ANCHOR_API_KEY});
  
  const session = await anchorClient.sessions.create({
    browser: {
      captcha_solver: {
        active: true
      }
    },
    session: {
      proxy: {
        active: true  // Required
      }
    }
  });
  
  console.log("Session created with CAPTCHA solver:", session.data.id);
})().catch(console.error);

​
Configure Text-based CAPTCHA solving

import AnchorBrowser from 'anchorbrowser';

(async () => {
  const anchorClient = new AnchorBrowser({apiKey: process.env.ANCHOR_API_KEY});
  
  const session = await anchorClient.sessions.create({
    browser: {
      captcha_solver: {
        active: true,
        image_selector: 'ol_capcha img',
        input_selector: 'ol-captcha input'
      }
    },
    session: {
      proxy: {
        active: true  // Required
      }
    }
  });
  
  console.log("Session created with text-based CAPTCHA solver:", session.data.id);
})().catch(console.error);
