List a customer's routable models
The models this customer can actually route to: the active catalog filtered by the customer’s effective controls (its own vendor, region and ZDR overrides over your organization’s), its key-usage mode (under BYOK_ONLY / CUSTOMER_ONLY a vendor needs a usable provider key), and your organization’s vendor access. Render a per-customer model picker from this instead of re-deriving the rules. A customer-scoped API key may read its own list.

Response
False when the effective controls restrict nothing; models is then the whole active catalog.
Models the controls allow but whose vendor your organization has not been granted access to. Routing refuses them today; access can be requested.
The key-usage mode the data plane enforces for this customer: its own, else your organization’s default for customers, else null (the organization’s own BYOK preferences apply).
