How about some technical documentation, in the form of
Documentation/technical/api-structured-output.txt (or something like
that), describing how this API should be used.

How about some tests?  Note that you need to take care of commits that
are encoded in encoding other than utf-8 (but with 'encoding' header,
so you know what encoding it is), and of filenames that are invalid
UTF-8 (and their encoding is unknown in general: they are raw binary
data).  You need to take care of non-ASCII characters, and of special
characters (like '"', SPC, TAB, LF, '\') in commits and in filenames.
