UK public sector APIs
This catalogue is for APIs published by public sector organisations in the UK.
If you’re working on an API that publishes open data or connects government with users from other organisations or wider industry, we’d like to invite you to publish details of it in this catalogue. You can publish details of your API by creating an issue in the API Catalogue GitHub repo.
Collecting a list of government APIs helps us understand:
- what APIs are published
- where API development is taking place
- whether APIs are suitable for reuse
The API catalogue also helps users across government find and access inter-departmental data exchanges, as well as sharing best practice in API development.
All of the APIs and data sources published in the catalogue have their own licensing and access restrictions. Check the documentation for each individual API for more details.
Note: An API appearing on this catalogue does not mean it will be publicly accessible, nor is it a requirement. This is a public-facing site to allow us to document and discover APIs that are available and in use.

The API Catalogue is a central part of the Data Standards Authority’s API programme, which aims to improve how APIs are produced, managed and used across government. For more information, or to ask to be added to the government API & Data Exchange community, email firstname.lastname@example.org.
If you have any questions about the catalogue, or how to add your APIs to it, email email@example.com.
If you are looking to set up an api.gov.uk domain for your API, email firstname.lastname@example.org.
