You pay for requests to the SmartCaptcha API made at https://smartcaptcha.yandexcloud.net/validate. You only pay for correct requests to which the API returns the ok status. Correct requests satisfy the following conditions:

• SmartCaptcha has identified the request as one sent by a human, not a bot.
• Correct secret and token values were provided.
• A unique token was issued not more than 10 minutes ago.

Examples of SmartCaptcha usage cost calculation:

1. The user has passed the CAPTCHA test resulting in a correct /validate request from the server. A fee will be charged.

2. The user has sent an empty or incorrect token resulting in an incorrect /validate request. No fee will be charged.

3. A backend developer has made a mistake and sent an incorrect secret or token in a response /validate request. The API will return an error in the message field. No fee will be charged.

4. An intruder has passed the CAPTCHA test, got a token, and sent it 10 times during the first minute. The API will return the ok status only to the first request, and you will be charged for the first request only.

5. An intruder has passed the CAPTCHA test, got a token, and sent it 10 times after 10 minutes. The API will return the failed status to all requests. You will not be charged for any of these.

You pay for the actual number of requests.

For example, if the price of 1 thousand validation requests is $0.800000 per month, and two hundred and fifty thousand and one request were made in a given month, your cost for the month will be:

(250,001 - 250,000) / 1,000 × $0.800000 = $0.000800
