Proxies

You can pass your proxy as an additional argument for methods: recaptcha, funcaptcha, geetest, geetest v4, keycaptcha, capy puzzle, lemin, turnstile, amazon waf, Cutcaptcha, Friendly captcha, MTCaptcha, DataDome, CyberSiARA and etc. The proxy will be forwarded to the API to solve the captcha.

Example solving reCAPTCHA V2 using proxy:

result = client.recaptcha_v2({
  googlekey: '6Le-wvkSVVABCPBMRTvw0Q4Muexq1bi0DJwx_mJ-',
  pageurl: 'https://mysite.com/page/with/recaptcha_v2',

  proxytype: "https",
  proxy: "proxyuser:strongPassword@123.123.123.123:3128"
})

Error handling

In case of an error, the captcha solver throws an exception. It's important to properly handle these cases. We recommend using begin rescue to handle exceptions.

  begin
  result = client.text('If tomorrow is Saturday, what day is today?')
  rescue ApiSolveCaptcha::ValidationException => e
    # invalid parameters passed
    puts(e)
  rescue ApiSolveCaptcha::NetworkException => e
    # network error occurred
    puts(e)
  rescue ApiSolveCaptcha::ApiException => e
    # api respond with error
    puts(e)
  rescue ApiSolveCaptcha::TimeoutException => e
    # captcha is not solved so far
    puts(e)
  end
