Welcome to the Daymet Single Pixel Extraction Tool API. You can use this API to download daily surface data within the Daymet database in a csv or json format for a single point. This API allows users to query a single geographic point by latitude and longitude in decimal degrees. A routine is executed that translates the (lon, lat) coordinates into projected Daymet (x,y) Lambert Conformal Coordinates. These coordinates are used to access the Daymet database of daily interpolated surface weather variables. Daily data from the nearest 1 km x 1 km Daymet grid cell are extracted from the database.

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.

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!).
