Nokia did not offer a free RESTful Geocoding API to the general public at the until recently (see below):
Obviously such a service does exist as here.com uses it, and the various APIs such as the Maps API for JavaScript are able to process geocoding requests using a nokia.places.search.manager, which in turn must be wrapping http calls to a RESTful geocoding service.
For Geocoding you have three options:
- You could use geocoding direct from the Maps API for Javascript - this is of course not RESTful
http://developer.here.net/apiexplorer/examples/api-for-js/places-search/search-by-address.html
- You could make an unstructured search by putting an address into the RESTful Places API. This a local search API and is not designed as a geocoder.
- You could contact Nokia directly (see the link at the bottom of the pricing plans page) and request a custom package including access to the "proper" geocoding service. This service would not be free, but would return proper geocoded results of a higher quality.
Updated:
As of Sept 2013, use of the RESTful Geocoding API is now available to signed in customers - the documentation can be found here
