Ok, so what is a captcha?

Captcha is “a computer program or system intended to distinguish human from machine input, typically as a way of thwarting spam and automated extraction of data from websites.” It stands for Completely Automated Public Turing test to tell Computers and Humans Apart.

Whether it be the next Twitter or a simple SaaS, captchas are important, however boring it may be, so that you don’t get the traffic you don’t want.
Now, you don’t need to waste your precious time into making a captcha then deciding on how to bypass the captcha and what not.

Let me introduce you to 2Captcha, a captcha solver which has an API for developers to implement captcha anywhere.
2captcha’s service provides an API that allows you to solve different types of captchas.
They don't offer a ready-to-use solution for custom tasks, but they have a
catalog of software integrated with the service where you can find software for your needs.

To use the service, follow a few simple steps:

  • Register an account


  • Check your balance and add funds accordingly.

  • Go to the settings page to get your API key and then copy and
    paste it in your software.


Now you are ready to start using your software with 2Captcha.

2captcha is a simple and quick way to get someone to solve your captcha. Just upload a text and it will be solved in 12 seconds.
2captcha is a Human-based captcha solving service, they have many workers who have signed up for this task. Their public statistics are listed below.

In March 2017 Google modified the ReCaptcha algorithm to shield it from an automatic answer. ReCaptcha now adjustments duties and pics oftentimes all through a solution on many famous websites and that is why solution time is multiplied. from time to time it takes extra than 2 mins due to the fact an actual human wishes a lot of time to bypass the ReCaptcha, despite the fact that it is solved manually as a regular person. This is why response times are affected a bit.
They have a variety of captcha to choose from. You can check the rates here.
Today, we’ll see how to implement SolveMedia image captcha with Java

They also have a referral program that allows to you share your own affiliate link, which when used to purchase from 2captcha, credits you 10% of the amount spent by your friend.

P.S: here’s my link, go use it.

You collect 10% of your affiliate earnings and 10% of any purchases your partner makes on the service (when, your partner spends money, sending captcha to a software, registering in the catalog, 10 percent deducted software developers, and you get only 5 percent of its expenditure on the captcha). Once a day, an affiliate is rewarded to the account balance. If your partner spends or earns money today, you will receive compensation tomorrow. $0,5 is the minimum payout amount. Payment must be requested on the page "payments for affiliate program," with the amount and method of payment specified. Depending on the payout direction, withdrawals are processed instantly or within 5 business days.

2Captcha is an automated captcha solution that uses the power of humans. Its goal is to improve reliability and make it possible for everyone.
