Where I can find location id of location when using Instagram API

I want to use Instagram API to get a list of recent media objects from a given location. I am using this URL. Now I can't do that, because I don't know where I should take location id?

1. First use facebook graph API to search locations and get facebook_places_id. Here is an example:

https://graph.facebook.com/search?q=&type=place&center=37.77493,-122.419415&distance=5000&access_token=ACCESS-TOKEN&expires_in=5184000

2. Get the facebook_places_id and use this instagram location search API to get the corresponding instagram_location_id

https://api.instagram.com/v1/locations/search?facebook_places_id=273471170716&access_token=ACCESS-TOKEN

3. Get the location id and then make the instagram location media API to get recent media:

https://api.instagram.com/v1/locations/514276/media/recent?access_token=ACCESS-TOKEN

Here is an implementation of Instagram location media search using the above method: http://www.gramfeed.com/instagram/places
