Top Geo Coordinate Conversion API Alternatives in 2025

As the demand for accurate geolocation services continues to grow, developers are increasingly seeking reliable APIs for geo coordinate conversion. In 2025, several alternatives to traditional APIs are emerging, each offering unique features and capabilities. This blog post explores the best alternatives to the Geo Calculator API, detailing their functionalities, pricing, pros and cons, ideal use cases, and how they differ from the Geo Calculator API.

1. Geo Calculator API

The Geo Calculator API is a versatile tool designed to calculate geo coordinates, geo fences, and celestial information. It provides four key features:

• Convert: This feature allows users to convert a list of geo coordinates into a standard format, including latlon, utm, mgrs, ecef, epsg3857, georef, and cartesian. For example, a request to convert coordinates might return:

{"coordinates":"N 39 48' 6.368\" W 86 9' 27.968\""}

This response indicates the converted coordinates in a standard format, which is essential for applications requiring precise location data.

• Distance: This feature calculates the distance between two geo coordinates. The response includes fields such as "meters" for the distance and "bearing" for the direction. An example response might look like:

{"meters":140596.58853321144,"bearing":141.94878033913545}

This data is crucial for applications that need to determine proximity or travel distances.

• Fence: The fence feature checks if a list of coordinates falls within a specified geo fence. A typical response could be:

{"insides":[true],"distances":[13438.80200086406]}

This is particularly useful for geofencing applications, such as tracking assets or sending notifications based on location.

• Sky: This feature calculates celestial information, including sun and moon positions, eclipses, and timings. An example response might include:

{"sun":{"isUp":true,"set":"2023-06-17T01:15:59","rise":"2023-06-17T10:17:17","altitude":48.81284808403095,"azimuth":99.6567012311506}}

This data is valuable for outdoor activities and astronomical observations.

2. Google Geocoding API

The Google Geocoding API is a powerful tool that converts addresses to geographic coordinates and vice versa. It offers two main features:

• Get Geocoding: This feature allows developers to convert a street address into geographic coordinates. A typical request might return:

{"address":"Jacarandaes 6207","latitude":"","longitude":"","status":"success"}

This response structure helps developers easily parse and utilize the geographic data in their applications.

• Reverse Geocode: This feature enables users to input latitude and longitude to retrieve the corresponding address. An example response could be:

{"address":"Hollywood, Los Angeles, CA 90028, USA","latitude":"34.101847299999996","longitude":"-118.326292","status":"success"}

This is particularly useful for applications that require location identification based on GPS coordinates.

3. Address Conversion API

The Address Conversion API transforms human-readable addresses into precise geographic coordinates. It features:

• Forward Geocode: This feature converts an address into geographic coordinates. A typical response might look like:

{"success":true,"code":200,"data":[{"lat":"41.8755616","lon":"-87.6244212","display_name":"Chicago, Cook County, Illinois, United States"}]}

This allows applications to accurately display locations based on user input.

• Reverse Geocode: This feature provides human-readable addresses based on geographic coordinates. An example response could be:

{"success":true,"code":200,"data":{"address":"520 S Michigan Ave, Chicago, IL 60605, Hoa K"}}

This is essential for applications that need to convert GPS data back into user-friendly addresses.

4. Coordinates Into Addresses API

The Coordinates Into Addresses API enables developers to convert longitude and latitude coordinates into human-readable addresses. Its main feature is:

• Coordinates Into Addresses: This feature allows users to input coordinates and receive a detailed address. An example response might be:

{"results":[{"formatted_address":"1435 W Pico Blvd, Los Angeles, CA 90015, USA"}]}

This is particularly useful for applications that require location identification based on GPS coordinates.

5. Location Translation API

The Location Translation API seamlessly translates addresses to coordinates and vice versa. It features:

• Location by Address: This feature requires an address parameter to return the corresponding coordinates. An example response could be:

{"results":[{"formatted_address":"Heritage Dr, Wells, Maine, 04090","geometry":{"location":{"lat":43.354661130292,"lng":-70.565013324596}}}],"status":"OK"}

This is useful for applications that need to convert user-friendly addresses into geographic coordinates.

• Location by Coordinates: This feature requires latitude and longitude parameters to return the corresponding address. An example response might be:

{"results":[{"formatted_address":" , 7, ,  , 660049","geometry":{"location":{"lat":56.018380506904,"lng":92.86716413352}}}],"status":"OK"}

This is essential for applications that need to convert GPS data back into user-friendly addresses.
