ThinkGeo Cloud Reverse Geocoding does not allow anonymous users to access the API. Before working with these APIs, you will need to register with ThinkGeo Cloud and create your own clients. A new account comes with two clients: NativeConfidential and JavaScript. See more details at here.

ThinkGeo Cloud provides standard RESTful APIs which can be consumed on any platform through any language. ThinkGeo also offers two prepackaged API clients to make it easier to integrate into .NET and JavaScript applications.

The SDK for .NET enables developers to build .NET application that uses the ThinkGeo Cloud services. The NuGet package can be found at ThinkGeo.Cloud.Client or you can install this package with PM by running the command: Install-Package ThinkGeo.Cloud.Client -Version VERSION_TO_BE_INSTALLED, here is the complete API List. Also you can check out the ThinkGeoCloudReverseGeocodingSample-ForWpf for the start.

• ThinkGeo.Cloud.ReverseGeocodingClient

  This documentation convers the ThinkGeo.Cloud.ReverseGeocodingClient class. It contains all of the members such as Constructors, Methods, Properties and Events.

The SDK for JavaScript enables developers to directly access ThinkGeo Cloud services from JavaScript code running in brower. This SDK can be found at thinkgeocloudclient-js. The ReverseGeocoding sample shows how to work with this SDK.
