Introduction to OS APIs
Explore API references, getting started guides and examples for developing with OS APIs.
Ordnance Survey (OS) APIs provide programmatic access to OS data and services. They offer a powerful gateway to rich geospatial data that empowers organisations and developers to integrate mapping information into their applications. You can use OS APIs to display a map, retrieve detailed location information for analysis and more.
OS APIs are grouped into: Maps, Features, Search and Utility.
The documentation on this site will help you to understand and utilise our APIs effectively, enabling you to create tailored solutions. Each API has its own overview page, technical specification, getting started guides and additional content relating to the specific API.
