List regions

Returns the Reactor regions you can target when you deploy a model, with the accelerators each region supports and your account’s accelerator allocations there.

Callers with the developer, account_admin, or user role may call it with an API key. Session tokens from POST /tokens are rejected with 403.

The response is advisory. Deployment admission makes the final decision, and supported accelerators can change as inventory changes. When inventory_status is unprobed, an empty supported_accelerators list means unknown, not unsupported; retry later.
