When you use data from Delphi’s COVIDcast Epidata API, we ask that you attribute the source and follow the terms of the data’s licensing agreement. The API contains some data streams produced internally by Delphi, which should be attributed to Delphi, and some republished from other sources, which should be credited. See below for details.
These data streams include data produced novelly by Delphi and intentionally and openly surfaced by Delphi through this API.
We request you attribute our data as follows:
