You need to get information about the number of challenges used over a certain period.

SolutionSolution

You can find the approximate number of challenges in the Monitoring section and select the desired period using the time filter.

Description of monitoring charts:

  • Checkbox captcha shows: Number of displays of the standard I'm not a robot button.
  • Checkbox captcha results: Number of responses.
  • Advanced challenge shows: Number of challenge displays.
  • Advanced challenge results: Number of responses in the pop-up window.
  • Validate results: Number of validations, the total number of responses.

You only pay for Validate results. To learn more about the relevant pricing, see this article.

You cannot use Monitoring to find out the exact number of requests; however, you can use the Yandex Cloud Billing itemization for this, if you enable product breakdown. There, you can see all requests to SmartCaptcha, whether successful or not.

You can export detailed information to a CSV file by clicking Export details. The exported file will include data on SmartCaptcha requests for each day, accurate to individual requests.
