First off, thanks for creating this API! It's very useful.

As I believe many people are now using this, I hope you keep the API and format stable, i.e. no breaking changes, such as changing the format of the dates, etc.

If you do see a need to make a breaking change, please consider adding separate endpoint URIs, such as with a version in the path or something.

Also, as a non-breaking change, is it possible to add a a top-level field to note the time the data was updated / processed in ISO format? Perhaps like this:

{
"confirmed": ...
"deaths": ...
"latest": ...
"recovered": ...
"source": ...
"updated": "2020-03-06T10:38:20.577Z"
}

Thanks again!
