Welcome to Natural Resources Wales' Dev & Test API portal
If you are a developer, you can discover and download our open data APIs for free. Sign up now for an API key to start using APIs from Natural Resources Wales right away, and to receive notifications of our latest data releases.
Our purpose is to ensure that the natural resources of Wales are sustainably maintained, enhanced and used - now and in the future.
Availability and resilience
While they are intended to be stable and robust, the open data APIs do not offer a guarantee of service level and should not be relied upon for safety critical applications. They do not replace the flood warning systems that Natural Resources Wales use to inform the public and partner organisations of floods and flood risk.
