Mock sample for your project: Routing API

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.

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).

IP2Location web service providing a service to do a reverse lookup of an IP address to an ISO3166 country code, region or state, city, latitude and longitude, ZIP/Postal code, time zone, Internet Service Provider (ISP) or company name, domain name, net speed, area code, weather station code, weather station name, mobile country code (MCC), mobile network code (MNC) and carrier brand, elevation, usage type, address type and IAB category. There are also 7 categories of additional add-on response fields supported such as metro, olson time zone, translations and more. Refer to https://www.ip2location.com/web-service/ip2location for further information.

Positioning API accepts requests with radio network measurements and replies with corresponding location estimate. For more details and examples, see Developer's Guide. Cellular measurements are given in terms defined in 3GPP and 3GGP2 specifications, see the corresponsing documentation at http://www.3gpp.org.
Breaking changes from v1:
JSON fields
altaccuracy, baselat, baselng, cellparams, pilotpower, pnoffset, powrx, rxlevel,
have been deprecated and replaced with
altAccuracy, baseLat, baseLng, cellParams, pilotPower, pnOffset, rss, rxLevel
respectively.
Dependent parameters combined as a subobject.
CDMA, GSM, WCDMA, TD-SCDMA and LTE local identification parameters for serving cell moved under localId property.
GSM neighbor global ID: lac and cid for neighbor cell moved under globalIdentity property.

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

GeoDataSource™ Web Service is a REST API enable user to lookup for a city by using latitude and longitude coordinate. It will return the result in either JSON or XML containing the information of country, region, city, latitude and longitude. Visit https://www.geodatasource.com/web-service for further information.

Routing consists of the following service:
Calculate Route
Calculates a route between an origin and a destination, passing through waypoints (if specified). Additional routing parameters like traffic, avoidance conditions, departure/arrival time etc. can be taken into account.
Calculate Reachable Range
Calculates a set of locations that can be reached from the origin point, subject to the available fuel or energy budget that is specified in the request.

Drive your app to success with Lyft's API

Background
This RESTful API provides information about physical VA facilities. Information available includes
geographic location, address, phone, hours of operation, and available services.
VA operates several different types of facilities, the types represented in this API include:
Health Facilities (vha)
Benefits Facilities (vba)
Cemeteries (nca)
Vet Centers (vc)
To read an FAQ on how wait times are calculated, click the "For more information" link on this page.
Getting Started
Base URLs
The base URLs for the VA Facilities API in the various environments are:
Sandbox: https://sandbox-api.va.gov/services/va_facilities/v0
Production: https://api.va.gov/services/va_facilities/v0
Authorization
API requests are authorized through a symmetric API token, provided in an HTTP header with name apikey.
Response Formats
Clients may request several response formats by setting the Accept header.
application/json - The default JSON response format complies with JSON API. This media type is not available for bulk requests using the /facilities/all endpoint. It will return 406 Not Acceptable.
application/geo+json - GeoJSON-compliant format, representing each facility as a feature with a point geometry.
application/vnd.geo+json - Deprecated. Prefer application/geo+json.
text/csv - Available for the bulk download operation only. Some structured fields are omitted from the CSV response.
Response Elements
Some data elements within the response are only present for facilities of a given type:
The patient satisfaction scores contained in the satisfaction element are only applicable
to VA health facilities.
The patient wait time values contained in the wait_times element are only applicable to
VA health facilities.
The list of available services in the services element is only applicable to VA health and
benefits facilities.
The operational hours special instructions contained in the operationalhoursspecial_instructions element is only applicable to VA health and Vet Center facilities.
Facility ID Formats and Constraints
A facility ID has the format prefix_stationNumber. The prefix is one of nca, vc, vba, or vha. Cemeteries may be national (VA) or non-national; non-national cemeteries have the station number prefixed with an s. There are no other constraints on the format. Examples:
Health: vha_402GA
Benefits: vba_539GB
National cemetery: nca_063
Non-national cemetery: nca_s1082
Vet center: vc_0872MVC
Mobile Facilities
The mobile health facilities move regularly within a region. If a facility comes back from this API with "mobile": "true", the latitude/longitude and address could be inaccurate. To get the exact current location, please call the number listed.
Deprecations
activestatus field is deprecated and replaced with operatingstatus.
application/vnd.geo+json media type is deprecated and replaced by application/geo+json
