i'm looking into writing a small app that would have contact's addreses (streetname+streetnumber, zip code, city, country) as input, use reversegeocoder to create gps coordinates and use them to set markers on a google map and display it on an internal website.
As I understand there's nothing like that in Hubspot (displaying contacts on the map), so is there an API endpoint that would display addresses ?
HubSpot doesn't have any native features for that, however there's a product on the HubSpot App Marketplace called Mapsly which can display contacts on the map (based on your address fields) and optionally auto-save GPS coordinates back to your HubSpot property.
