What is “Rate per second”?

This rate sets a limit for requests that can be made per second. The default equals 10, which means at most 10 requests can be done in a second. Still, this logic does not apply to all time frames.

For 1 minute time you can use up requests equal for max 30 seconds, which means that 1 minute allows max 300 requests. The same logic goes for 1 hour, where you can use up requests equal for max 30 min, which means 9 000 requests.

How many credits does an endpoint cost?

You can see the credits cost for each endpoint in our official Documentation. Simply select the endpoint you want information for and the credits cost is displayed at the end of the page.
