Captcha recognition

How much does 1000 captcha recognitions cost?

Price is influenced by server workload from number of captchas and number of workers online. The price is the same for all webmasters at the same moment and ranges from 0,5$ to 1$. You can check current rate by API or at SolveCaptcha API. Webmaster can adjust his maximum rate per captcha. When the rate is higher than set by the webmaster captchas wouldn't be uploaded and webmaster will receive :ERROR_NO_SLOT_AVAILABLE:

How is recognition price is formed?

Price is based on server workload. Minimal price is 0,0015$ for one recognition – 0,15$ per 1000 captchas, maximal price is   0,0006$ for one or 0,66$ per 1000 captchas. When there are few solved captchas sent to the server then the price drops and vice-versa. Price wouldn’t go higher than 0,66 per 1000 (but the rate can be increased for big captchas, recaptchas, etc.)

I received ERROR_NO_SLOT_AVAILABLE what does it mean?

 That means that current rate on the server is higher than the one you selected in settings. Reminder: you are charged current rate at the moment you upload images, not the maximum rate from your settings. If the current rate on the server is higher than yours  you will receive ERROR_NO_SLOT_AVAILABLE and your captcha wouldn’t be accepted.

Refunds for incorrectly recognized images

To receive refund webmaster has to inform server about incorrect recognition. Either through reportbad function or manually by clicking “incorrect recognition” on the “loaded captchas” page. Complaint must be issued during 15 minute gap starting from the upload of the image. After that server wouldn’t accept the complain and will return ERROR_WRONG_CAPTCHA_ID. After an issued complaint worker’s account is bloked for the sum of the complaint and worker has 2 days to dispute the complaint or to agree with the blocked sum for incorrect recognition. After 2 days money for incorrectly recognized captchas is returned to webmaster, excluding cases when worker disputed webmaster’s decision and moderators agreed with workers position.

How long is uploaded captcha stored at the server, how long can I get the reply or complain?
