World Check rate limit and request quotas

Hi,

Our integration is planned to save a case, get the screening results, then get the world check profile for each result. We will have one api key per customer (rather than user), but have no way to manage requests between users on the same key/secret.

I'm concerned that for large cases, we may hit rate limits. Could you give an indication of the standard rate limits on the world check api, and any penalties you apply for exceeding it?

Thanks.
