REST API Overview

The REST API allows you to develop custom geodetic applications for any platform, mobile or desktop (e.g. Android, iOS, Windows, MacOS)

With our APIs you can transform coordinates, calibrate coordinate systems, query for elevation data. It's based on managing resources via the HTTP methods GET POST PUT and DELETE. All requests to the REST API are made to the same host: and over HTTPS.


All requests must include a valid API Key for authorization. An API key is a token that a client provides when making API calls. Generate API Key and send it as a request header 'API_KEY: [your_api_key]' for every request.


Only JSON is supported in the REST API. Other content types are currently not supported and may produce unpredictable results. Request bodies should supply JSON data and responses will come back as JSON.
