One endpoint, every model.
Point the SDK you already use at one URL. Each call goes to the model you name, or the cheapest one that passes a check you set (a test, a schema, a judge), and every call is recorded with what it cost. Over a plain key you get routing, checks, one bill and the record.
# Keys come from the waiting list; this URL answers once you have one.
