Mock sample for your project: Visual Crossing Weather API

Weather Forecast and Historical Weather Observation Data via an convenient, restful 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.

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 requests must contain a key "API-Key" in the header (see code samples). Obtain a key from here.

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!).

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.

Global marine weather data from multiple sources in one single API with hourly resolution. Get your API key by visiting the Storm Glass web site.

IP2Proxy allows instant detection of anonymous proxy, VPN, TOR exit nodes, search engine robots (SES), data center ranges (PX2-PX10), residential proxies (PX10) and VPN provider name (PX11) by IP address. It also returns the threat type of the proxy (PX9 or higher). Visit https://www.ip2location.com/web-service/ip2proxy for further information.

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

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).
