From $0.5 to $1 for 1000 CAPTCHAs solved
The current bid for 1000 CAPTCHAs depends on the number of images the system receives at the moment and the number of workers online. It is easy to calculate: if the number of incoming images is less than ‘number of workers online*4’ then the bid is minimal and equals $0.005 for one solved CAPTCHA. In case the number of workers has decreased or the number of incoming images has increased, the bid grows gradually. The bid never surpasses the figure of $1 for 1000 CAPTCHAs so that is the maximum bid for the system on the peak hours.
Special 100% Accuracy Features for Complicated Images
2Captcha provides 98% average accuracy rate, one of the highest on the market. Sure enough, you pay only for correctly solved CAPTCHAs. At the same time we offer a special algorithm for 100% accuracy that you can use for special kind of images. When you use this feature, a single incoming image is sent to multiple solvers. Then, our unique algorithm compares their answers and checks if they match. The algorithm picks the value that has most matches and returns it to you. You can find out more about the 100% accuracy feature here (the page is available after you register at 2Captcha.com)

You are charged only in case the image is recognized correctly. There are two ways to report an incorrectly solved CAPTCHA:
  1. he reportbad command sent via API
  2. The ‘Report’ button in your 2Captcha interface
In order to avoid mistakenly reported CAPTCHAs, we let the worker check the reported CAPTCHA with the moderator within the next 3 days. This manual check ensures that the system works correctly. After the reported CAPTCHA is recognized as incorrect, you get refunded for this CAPTCHA.
