For this example we want to find all broadcasts televised in the county that corresponds to a geopoint (latitude and longitude coordinates).
The location.origin parameter allows us to filter broadcasts by a geopoint, such as the location of a store. The Broadcasts API returns broadcasts for the county the geopoint is located in. For our example, we have a store located in Union Square, San Francisco, which has a latitude of 37.7879 and longitude of -122.4097. So we will use location.origin=37.7879,-122.4097. Using these coordinates will return broadcasts for San Francisco County - the county which Union Square is in.
We can also use the sort parameter to order the broadcasts returned by the API. For our example, we will use sort=-start to return the most recently televised broadcasts first.
