To prevent clients from getting hit with an IP ban, there is a built-in delay. You may not call the API more than once every five minutes, and if RDG goes over quota, there is a 30-minute delay between quota checks.
If you need a lot of numbers, or think you will need more numbers in the near future, request them all at once. Don't issue a lot of requests for small amounts of numbers. Make a single large request and then store the extra numbers somewhere until you need them. Otherwise, RDG will simply bypass the RANDOM.ORG API and you will be getting random numbers from Excel instead.
