Search capabilities with supplied data

I searched other topics, but did not find anything that answered this question:

I would like to allow users to search based on their address against addresses that are submitted from my database. Is this possible with the tomtom API?

Basically, I have a set of providers who submit their addresses and I would like users to find the providers that are within a certain radius.

Thank you in advance!

Is this radius a fixed value or a user will be able to define it?
