Search results
When requesting results from Mapzen Search, you will always get back GeoJSON results, unless something goes terribly wrong, in which case you'll get an error message.
Tip: You can go to http://geojson.org/geojson-spec.html to learn more about the GeoJSON data format specification.
The top-level structure to every response looks like this:
{
"geocoding":{...},
"type":"FeatureCollection",
"features":[...],
"bbox":[...]
}
##List of features returned
The features property of the result is where you will find the list of results that best matched your input parameters.
Each item in this list will contain all the information needed to identify it in human-readable format in the properties block, as well as computer friendly coordinates in the geometry property. Note the label property, which is a human-friendly representation of the place, ready to be displayed to an end-user.

Result count
By default, Mapzen Search results 10 places, unless otherwise specified. If you want a different number of results, set the size parameter to the desired number. This example shows returning only the first result.
