In the next few weeks I will add a limit to the api requests. It will be something like 2500 requests per hour.
If you are currently using the api, think about caching the data. If you know you will need more than 2500 requests because your service requires uncached results, please contact me in discord so we can talk about it.
Most of the current api users will never reach the limit, but there are a few users who will receive a "Rate limit exceed" message when using the api.
