Is there a request limitation for each Project ID per day or per hour?

At the moment there is not a fixed rate limit number, as this varies depending on the available bandwidth of the shared infrastructure cluster. We do our best to keep this well provisioned for the community and we expect that this will be adjusted in the near future.

Any information pertaining to rate limiting of the API will be documented on our official docs and we will update the community as this information is rolled out.
