Our Partners can help you unlock the power of OS data and APIs.

Get started with APIs

Work through tutorials and use copy and paste examples.

Here’s how using APIs can benefit your organisation

APIs are another way of accessing OS data. The overriding benefit of using APIs is that they make data management more efficient, saving you time and resources. An API gives you direct access to up-to-date data, which means you don’t have to spend time downloading and managing data.

Find out how OS data and APIs can help the Public Sector

Health and Social Care

The need for accurate addressing data has never been greater for the health and social care public sector.


The environment is a huge priority for the public sector in the coming years as the UK was the first to pass net zero carbon emissions into law.

National Security and Resilience

Managing emergencies is a major part of the challenge of creating safe communities.


It’s clear from ‘The Planning for the Future’ White Paper published in August 2020 that planning reform would be a key priority for the public sector in coming years.


With government transport policy committed to getting people moving around quicker and safer in future years, the onus is on the public sector to adapt to meet those challenges.

Our APIs have been tried and tested

Our partners and members have been using our APIs through the OS Data Hub since July 2020.  Here’s what some of them had to say.


“The PSGA has brought about faster and greater access to data in the form of OS APIs and the OS Data Hub. The APIs allow for direct and fast integration with these data sets and opens the door to developing more complex web mapping services for use internally or publicly.” 


"OS have invested a great deal of time and effort in the OS Data Hub, and we at Cadcorp have no doubt that it is a practical, sensible and desirable way of delivering OS data, and that it is here to stay." 

Bournemouth, Christchurch and Poole Council

"I’ve tested the OS Maps API in QGIS and set up a couple of Projects for people that I’ve worked with this week, just to get a feel for user feedback… initial response is brilliant rendering speed for those working at home, users overjoyed! Really like the simplicity and functionality of the (OS Data Hub) dashboard as well.”

Introducing our location APIs

There are different options for accessing and using OS data and which one you choose will depend on your use case.

Which geospatial API do I need?

We want to help you choose the right geospatial API for your use case by presenting a series of user stories and recommending the API that is the best fit.
