Project Tycho API
Project Tycho is an open-access repository for global health surveillance data, built and run at the University of Pittsburgh and served from www.tycho.pitt.edu. It holds case counts for 78 notifiable conditions in the United States, dengue for 100 countries and COVID-19 for 237 countries, standardized into the Project Tycho Pre-compiled Data Format version 1.0. The API is fourteen GET endpoints returning CSV: thirteen listings that enumerate the controlled values of each variable in that format, and /query, which returns the surveillance rows filtered on any of them. Every call carries a free API key in the query string. The site is maintained for Project Tycho by the MIDAS Coordination Center under NIH/NIGMS grant R24GM153920 and is copyright University of Pittsburgh. Pitt publishes no machine-readable contract for it; the OpenAPI in this repository was written by API Evangelist from Pitt's own published reference.
