Every time your site receives a comment, it makes an API call to Akismet to check whether the comment is spam.
Akismet’s plans have limits on the number of API calls your site can make per month.
How can I see my API usage?
At the bottom of your Akismet Account page you’ll see “Click here for account-wide spam stats”. Click that link to view stats for your API key. You can check the TOTAL API CALLS column to see your monthly API calls.
Why is my site exceeding the limit?
It’s possible that your site may exceed the monthly API usage limit because it generates a lot of traffic and thus a lot of legitimate API calls. In this case, we’d expect to see the API limit exceeded consistently every month.
It’s also possible that your site may exceed the limit as a result of something outside of your control, such as a targeted attack on your site from spambots. In this case, the overuse may be an isolated incident, and could fall within the limit again the following month.
What happens if I go over the limit?
We’re aware that sometimes your site may exceed the API usage limit for reasons beyond your control, as mentioned above, so the first time you exceed the limit, we will not take any action, and Akismet will continue to work as normal.
If you exceed the usage limit for three consecutive months, then we will deny any additional calls until the end of the third month (or until your plan is upgraded).
The same thing will happen for each consecutive month that your limit is exceeded. Any calls beyond the limit of your plan will be denied until the end of the month (or until your plan is upgraded).
Note: The API usage limit is reset at the end of each calendar month, it is not based on your purchase/renewal date.
