The ProPublica Forensics API allows access to data from Propublica's investigation into the quality of autopsies across America. The API provides "state and county-level data about coroner and medical examiner systems in the United States." The RESTful API is available in JSON, XML and JSON-P formats. An astounding variety of data are available, from the ratio of autopsies to what is expected, to the number of uncertified pathologists working in a state or county system, and on and on.
The biggest value that WattzOn is offering through its WattzOn API is access to its “Embodied Energy Database” (EED). This database seeks to detail the amount of energy required to manufacture, transport, use, and dispose of all our stuff. The idea is that if we knew the embodied energy in all the items we use, we could make better consumption choices, avoiding those items with unexpectedly high embodied energy.
