I think you might be thinking of api's from companies like Verisign,
which are online payment processors.  Online payment processors in
turn connect to direct processors such as Firstdata, Vital, Global
Payment, etc..  Those direct processors do not have open-spec API's,
at least none of them that I have worked with and I've certified with
most of them at one point or another.
