System
Builds decision services for the models on one System One endpoint. Every service the factory builds shares one HTTP client and one key supplier.
Building a service never resolves the key or contacts the endpoint. The key is read on each call, so a rotated key takes effect on the next call. A blank key sends no Authorization header, which suits endpoints that need none. The endpoint's binding validates the default model at construction, before credentials are read.
When restClientBuilder is given, a clone of it is used, so its transport, interceptors and timeouts apply. Otherwise the factory builds a client with the endpoint's timeouts that does not follow redirects.

Functions
Returns a service for the default model.
Returns a service for the named model. The endpoint's binding checks the name first, and the endpoint decides whether a model it accepts exists.
Reads the key once, checks it by listing the endpoint's models with it, then returns a service for the default model. A missing key, a rejected listing or an unreachable endpoint all count as an invalid key. A key supplier that throws InvalidApiKeyException itself, as one that insists on a key does for a blank one, counts as a missing key. An already interrupted caller is cancelled before the key is read, including when no key is configured. An interrupted key supplier also throws a CancellationException.
Lists the models the endpoint serves.
