I saw code snippets where people use the curl to catch the captcha image, but it is possible to catch the string that is in the picture ?
From what I understand, the complexity of catching captcha depends on the code that each site uses to generate it, that’s right ?
For example, what script would be responsible for generating catpcha of this link here ?
So it is not possible to create a universal code to catch the captcha of the site ?
The CURL takes anything that is on the page, simple like that, including the image. Then use OCR to try to get the words/letters that are in the image or you can use voice recognition and use captcha in audio mode. The difference is that each Captcha is a captcha, there is no way to have something universal. Some are mathematical operations, others are excerpts from books, others are images that contain some X thing, others are random words, others are advertisements.... If there are several types of captcha, how would there be "a universal code"?! The principle tends to be the same.

Hmmm got it, it makes sense. Do you know any free ocr library ? or any ocr api I can use for this ?
