Hi HN - I’m one of the team working on Covid Act Now. We’re hoping this API is a useful input into COVID efforts (response planning, reopening initiatives, data visualization, etc).<p>Our model is only scoped to the USA (I wish we could include more countries, as this is a global pandemic. We haven’t had the time to expand yet).<p>I’m sure the API could be improved in the next version. For example, we had some lively discussion around whether OBSERVED_INTERVENTION was intuitive enough variable name. (It uses an inferred R0 based on actual observed deaths, cases, and hospitalizations to generate forward projections).<p>If you have any feedback, let us know and we’ll try and make it better in V2.
