Mock sample for your project: OpenCage Geocoder API

API for OpenAQ LCS

Search API is a RESTful API that allows developers to run a single line fuzzy search for addresses and POIs. Search API returns the latitude/longitude of a specific address, cross street, geographic feature, or point of interest (POI).

Use this JSON API to build and test radio links for any radio, anywhere. Authenticate with your API2.0 key in the request header as key

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 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!).

The general-purpose API

Space has a hostile radiation environment that increases the risk of cancers in humans and malfunctions in spacecraft electronics. The types of space radiation of primary concern are:
Galactic Cosmic Rays from outside our solar system generated by
supernovae and other phenomena;
Solar Energetic Particles produced by the Sun during intense and
sporadic bursts of activity; and
Trapped Radiation: energetic particles confined by Earth's magnetic
field, usually comprising an inner belt of mostly high energy protons
and an outer belt dominated by lower energy electrons and plasma.
Understanding the space radiation environment for a particular mission profile is becoming increasingly important. Commercial off-the-shelf electronic components that aren't resilient to space radiation are now prevalent. Longer duration missions to cislunar space, Mars, and beyond are placing astronauts at greater risk of radiation exposure.
API requests must contain a key "API-Key" in the header (see code samples). Obtain a key from here.
