I am writing a small js/html5 app to monitor my internet connection. For this I need to "ping" an external service to check if the device is connected to the internet. Httpbin/status/200 seems to be just what I was looking for, however my app will ping the service every 3 seconds or so (e.g. that means a peak of 28k times a day).
For me only using it, I guess that will be okay, however I plan to release it on github, so hundreds of users will probably start to use it.

Do you have any quota limit in place that I should be aware of before releasing it?
