It's not snappy but you could substitute "REST" for "HTTP" and end up with
REST-VC-Issuance, REST-VC-Verification, etc, in whatever order suits you.

(An argument why this is good, is that it describes the purpose, which is
that you want to define a REST interface, and while it happens that any
solution for that other than HTTP might be an odd design decision, that
doesn't have to be reflected in the name.)

More pronounceable anyway.


PS I've not had time to follow this as closely as I'd like, so apologies if
I'm not making sense, but where people are questioning the need for this
kind of protocol, I'd like to float a potential use case, which is that
where OIDC mandates "UserInfo" as a restful endpoint for a bunch of user
data, something along the lines of an "issuer" VC API might well be much
more suitable and scalable. These specifications don't have to concern
themselves with how a client may be authenticated or authorized, in order
to be exceedingly potentially useful :-)

PPS I just saw Kerri's email, and I like that way of thinking too!
