Hi Donna,
I took a look at the Foobot API (http://api.foobot.io/apidoc/index.html). It looks pretty straightforward, although its not clear through the documentation how to get an API key if you don’t have an account nor how to get an account if you don’t have a device. Conceptually, though, the API is close to a lot of other cloud APIs that work well with CODAP. To give you a sense of this, here is a CODAP document that accesses periodically the USGS database of recent earthquakes of magnitude 2.5 or more: https://codap.concord.org/app/#shared=36160 . Although it is a quite different subject matter, it is, with respect to being “live”, similar to the application you have in mind, as I understand it.
