There isn't a JSON transport protocol either. And EDI is not a format; it's a general reference for multiple data standards and the rules for exchanging data instances of them. One of the issues is that people have different opinions of what EDI is, which is confusing, pretty much as what their views about API are. Although the definition of EDI and API is expected to be "standardized", everyone seems to have their own flavor of it :) Pun intended.
