Geographic data - API calls

Quick question here. I have a list of geolocated entries - each has a “location” field, which gets populated via an API. All good so far.

Most of my searches are geographical, based on :extract queries, e.g., find me all records with locations in Maine.

Do these searches trigger Google Maps API calls, or are all components of the Google Maps API geolocation queries stored once and for all in the DB when the location field is set?
