Updated: 11 January 2021
We’ve introduced a new range of location APIs that you can access via our OS Data Hub. They all give you access to OS OpenData, and the option to upgrade to premium data (unless you’re a public sector member, as you’ll be using the Public Sector Plan), and you can get started for free on the OS Data Hub.
There are different options for accessing and using OS data and which API you choose will depend on your use case. You may want to download datasets and have access to all the features locally or offline. Or you may prefer direct access to the maps or data you need, as and when you need them, via the internet – and this is where APIs are useful.
Update: 1 July 2020, OS Data Hub now live, sign up here
The OS Data Hub is the new way to access our authoritative location data. It will replace the current OS ordering systems (OpenData Portal, OS Orders and API shop) with one mobile-friendly platform with a single sign on to give you a better user experience.
