Yes you can retrieve list of business around your location, your query will be as follows,

MQL query: {"lat": 37.75629, "lon": -122.4213, "radius": "1km", "entity": [{"type": "business", "guid": null}]}

GeoAPI url query: http://api.geoapi.com/v1/q?q=%7B%22lat%22%3A+37.75629%2C+%22lon%22%3A+-122.4213%2C+%22radius%22%3A+%221km%22%2C+%22entity%22%3A+%5B%7B%22type%22%3A+%22business%22%2C+%22guid%22%3A+null%7D%5D%7D&apikey=demo&pretty=1
