Mock sample for your project: World Time API

API de Dados Abertos com dados processados pelo grupo de monitoramento de Queimadas do INPE.

The Maps API web services suite offers the following APIs:
Raster
The Maps Raster API renders map data that is divided into gridded sections called tiles. Tiles are square images (png or jpg format) in various sizes which are available at 19 different zoom levels, ranging from 0 to 20. For zoom level 0, the entire earth is displayed on one single tile, while at zoom level 20, the world is divided into 2 40 tiles.
Vector
Similar to Maps Raster API, the Maps Vector API serves data on different zoom level ranging from 0 to 22. For zoom level 0, the entire earth is displayed on one single tile, while at zoom level 22, the world is divided into 2 44 tiles.
The Maps Vector Service delivers geographic map data packaged in a vector representation of squared sections called vector tiles. Each tile includes pre-defined collections of map features (points, lines, road shapes, water polygons, building footprints, ect.) delivered in one of the specified vector formats. Format of the tile is formally described using protobuf schema.

Since 2006, Gisgraphy is a free, open source framework that offers the possibility to do geolocalisation and geocoding via Java APIs or REST webservices. Because geocoding is nothing without data, it provides an easy to use importer that will automatically download and import the necessary (free) data to your local database (OpenStreetMap, Geonames and Quattroshapes: more than 100 million entries). You can also add your own data with the Web interface or the importer connectors provided. Gisgraphy is production ready, and has been designed to be scalable(load balanced), performant and used in other languages than just java : results can be output in XML, JSON, PHP, Python, Ruby, YAML, GeoRSS, and Atom. One of the most popular GPS tracking System (OpenGTS) also includes a Gisgraphy client...Gisgraphy is a framework. As a result it's flexible and powerful enough to be used in a lot of different use cases. read more
if you use the premium servers, you can use the api key to test the webservices

The gravitational field of the earth is non-uniform. The geoid is the shape the
ocean surface would take if only gravity and the rotation of the Earth
were considered. The geoid is the surface that defines zero elevation.
The geoid height is the difference between an ideal reference ellipsoid and the geoid.
The gravity anomaly is the difference between the acceleration due to gravity on the Earth's surface and the value calculated assuming the reference ellipsoid.
The official Earth Gravitational Model EGM2008 was developed and released to the public by the National Geospatial-Intelligence Agency (NGA).
Our EGM2008 API provides on-demand access to the EGM2008 model, as implemented by the open-source GeographicLib Gravity library.

API for the Water Linked Underwater GPS. For more details: http://www.waterlinked.com
Recommended approach for connecting to a Underwater GPS via the API is:
If "GET /api/" times out, the Underwater GPS is not running (on this IP address)
If "GET /api/" responds with 200 OK check that the api version returrned (eg "v1") is supported by the client (eg: also supports "v1").
If the api version returned does not match what the client supports: give an error to the user and recommend upgrading. (Eg: response is "v2" while client only supports "v1")
If "GET /api/" responds with 301 Moved permanently. "GET /api/v1/version" to check if the kit has a version earlier than 1.5.
"GET /api/v1/version" will always respond with 200 OK on Underwater GPS earlier than 1.5 release.
Configuration API is is not considered stable and will potentially be changed
