About the API


M+ is embracing open access and working towards releasing as much of our collections metadata as possible. Our goal is to unlock the museum’s institutional knowledge and release it into the public domain, driven by M+’s mission as a public institution. Read more about our open access journey here and here.

We’ve released an open data set here, but are also sharing our data through a public API to help increase access and encourage creative projects. The M+ API will be available for anyone who’d like to work with it. It’s for developers, designers, artists, creators—anyone who’s curious about telling stories through data.

The data

The data made available to you through this API service is a reflection of institutional knowledge developed over time at M+. This data has been created by curators, registrars, researchers, and scholars working in collaboration with M+ to describe, express, and interpret the objects held in the M+ Collections. This data is made available to you, the public, as CC0 Open Data and through this API service, for use by your websites, applications, and research projects.

This data is provided ‘as is’ for research purposes and you may use it at your own risk. Documentation of the museum’s collection is an ongoing process and we are continuing to research and enrich our collections data. We will update the dataset with new and revised information on a regular basis. M+ makes no representations or warranties of any kind on this data.
