Book a 30-minute call
Free. Bring whatever you know about what your teams currently send to model APIs — even a rough monthly figure and a list of tools is enough to make it useful.
You leave with a view on whether a gateway and routing setup makes sense, what it would cost, and what the first steps would look like. If the honest answer is that you should not do this yet, we say that on the call.
OR
Read by a person, replied to by the same person, usually within a working day. Fine for "we are not ready but here is our situation" — those are often the better conversations anyway.
