Hello @Hope estheim ,
You mention downloading an SDK, may I ask what platform you are targeting? Note that you can try Bing Maps Autosuggest at https://www.bing.com/api/maps/sdkrelease/mapcontrol/isdk specifically under the left menu topic "Services" https://www.bing.com/api/maps/sdkrelease/mapcontrol/isdk/autosuggestui.
Sincerely,
