About the API

The SFTool API is simple, yet powerful. With it, you can surface a myriad of high performance building information. You will need to signup for an API key at https://sftool.gov/developer/apikey-signup/.

All of our API methods are HTTP GET and always return the latest data. Whether you’re looking to add sustainable building information to your website or blog, or using this data to build an application, the SFTool API is here for you.

Making API calls is very straightforward. Our API is fully REST and provides semantic URIs to deliver the resources.
