solveCaptchaBase64()

solveCaptchaBase64(base64String [, callback])

Solves a CAPTCHA image.

This method takes a Base64 encoded image and sends it to one of our partners for solving.

If your CAPTCHA image is trivial, an OCR algorithm will quickly return the text, otherwise a human will solve it. This process generally takes less than 30 seconds and accuracy is >90%.

When a result string is returned, 1 is substracted from your daily CAPTCHA counter. In less than 10% of the cases the result will be incorrect — retry at will.

This method is asynchronous and returns nothing.
Use the callback to know when it has finished.

— base64String (String)

CAPTCHA image to solve.
Can be pure Base64 or a Data URI Scheme string starting with data:.

— callback (Function(err, result))

Function called when finished (optional).

  • err (String): null or a description of what went wrong if something went wrong.
  • result (String): the solved CAPTCHA text.
