Nearby service API

We’ve developed a nearby service with our API that helps websites like Skyscanner and other cheap fare finders to locate airports nearby certain positions. You can input coordinates of cities or airports and a certain distance range and the response will be the airports and cities in that range plus their distance and detailed information about the targets. Our airport and city data comes from government sources and other aviation authorities as well as airport providers themselves. We host this on our server in Europe which has an uptime of 99.95% making the service always available to you.

What is in our database

How we classify it

The foundation of our nearby service API is the database of airports and the database of cities. Of those endpoints, we have collected detailed information. For example the IATA, ICAO, timezone, related country and other useful information. Of course most importantly for this API, location coordinates of these cities and airports. These are given in latitude and longitude.

Those are also available through the API system so you can integrate further details if needed. You can find the exact list of data which will be given as output with the nearby service below.

Why we choose this information

The reason we chose this data given by the nearby service API is that it matches exactly what our clients have requested in the past. It offers useful value points like IATA and ICAO codes which can be used to connect to further data if required.

An example: Say you have a city and want to find nearby airports, our API can do this. The response will be a list of nearby airports and possibly cities also. Let’s say you want more information about the airport. You can get this from the airport database and API which includes more details such as the translations of the airport or contact information and the country it is in. Following up on that, you could obtain detailed information about the country as well.

There is no limit of the amount of data in our API and we’ve decided to segment it in usable formats.

How do we guarantee the accuracy

The data used by our nearby API is based on the cities and airports database which is collected from hundreds of sources. From government to other authority partners in aviation. Our software automatically updates the data constantly and if there is any incorrectness noticed by our software, we are alerted. We maintain direct communications with our sources and will verify the data when needed. This keeps us always on top of the data.

Method of data collection

The way the data is collected – by first creating a base of information. In this case, it’s a gigantic list of airports and cities. Piece by piece we collect further data on these subjects. Starting with ICAO and IATA codes. On top of this foundation, we add the details that make our database so valuable. We constantly build upon our database and increase the amount of information that we provide.
For this API we’ve developed the software built upon these databases to provide you with the fast response on which airports or cities are nearby a given latitude and longitude coordinates.

About our sources

Due to the nature of our broad database, we need information from many sources. Currently, we have in the hundreds of original sources from which we gather information. These can be divided into two types: authoritative sources and other official original sources. The authority sources are government or recognized aviation authorities. We obtain our data only from original sources. Our other non-authoritative sources can be airport or airline companies for example.

We validate each of our sources and do our best to maintain a direct line of communication with them.

Some of our biggest clients are booking websites where one company may use our API for a range of their platforms on websites as well as mobile applications.

Not sure if this would be a real-world application but it’s great to see how creative our clients are with the use of our information.
