Every API call must include an API Key, which is unique for each client, as in the following examples.
http://api.v1.trippinin.com/match/[place name]?coordinates=[lat,lng]&KEY=[your API key]
http://api.v1.trippinin.com/match/Hard Rock Cafe Barcelona?coordinates=41.38605,2.1700&KEY=298jkefwhfjwe82323h
* When the API key is the request’s first parameter, the [&] should be replaced with a [?].
We've assembeled a bounch API calls that should answer most if not all of your needs.
