Increase rate limit for application

hello, is it possible to increase my api rate limit from the default 600 to 1200 or 1800?

many thanks

I have a similar question is it OK to request 600 records every 5 mins 24x 365 days per year. A bulk download which we can download ourselves would be the ideal solution.

It is ok, but the API is not intended for this sort of data harvesting.
We have a number of bulk products that may be of more use to you.
I have passed your details onto our customer care team who will contact you directly.
