Mock sample for your project: LotaData API

The GeoDB API focuses on getting global city and region data. Easily obtain country, region, and city data for use
in your apps!
Filter cities by name prefix, country, location, time-zone, and even minimum population.
Sort cities by name, country code, elevation, and population - or any combination of these.
Get all country regions. Get all cities in a given region.
Display results in multiple languages. RESTful API adheres to industry best-practices, including
HATEOAS-style links to facilitate paging results.
Backed by cloud-based load-balanced infrastructure for resiliency and performance!
Data is periodically refreshed from GeoNames and WikiData.
Notes:
Since the database is periodically updated, this may very rarely result in certain cities
being marked deleted (e.g., duplicates removed). By default, endpoints returning city data will exclude
cities marked deleted. However, in the unlikely event that this occurs while your app is paging through a set
of affected results - and you care about the paged results suddenly changing underneath - specify
includeDeleted=SINCEYESTERDAY (or SINCELAST_WEEK if you're really paranoid!).

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

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
