Documented steps
All management calls go to base URL https://api.baseten.co with header 'Authorization: Bearer <BASETEN_API_KEY>' (legacy 'Api-Key <key>' also accepted).
List models: GET /v1/models (optional ?name= filter). Response contains id, name, created_at, deployments_count, production_deployment_id, development_deployment_id and instance_type_name.
List a model's deployments: GET /v1/models/{model_id}/deployments. Each entry carries id, name, is_production, is_development, status, active_replica_count, autoscaling_settings, instance_type_name and environment.
Read one deployment: GET /v1/models/{model_id}/deployments/{deployment_id}, or use the /production and /development shortcuts in place of the id.
Update autoscaling: PATCH /v1/models/{model_id}/deployments/{deployment_id}/autoscaling_settings with any subset of min_replica, max_replica, autoscaling_window, scale_down_delay, concurrency_target, target_utilization_percentage, target_in_flight_tokens and max_scale_down_rate (1-50). Only fields you send are changed.
The PATCH response returns a status of ACCEPTED, QUEUED, or UNCHANGED. Treat the call as asynchronous.
Activate a deployment: POST /v1/models/{model_id}/deployments/{deployment_id}/activate with an empty JSON body. Deactivate: POST .../deactivate.
Confirm the change by re-polling GET /v1/models/{model_id}/deployments/{deployment_id} until status and active_replica_count reflect what you asked for, rather than assuming the PATCH applied instantly.

Known gotchas
An autoscaling PATCH can return QUEUED or UNCHANGED rather than ACCEPTED. Code that assumes immediate effect will read stale replica counts.
min_replica: 0 permits full scale-to-zero and therefore cold starts. scale_down_delay controls how long an idle replica stays warm - and you are billed for that warm window.
The /production and /development shortcut paths resolve to whichever deployment currently holds that environment. Passing a deployment id that is not bound to that environment returns 404.
Deactivating stops compute billing but does not delete the deployment or its configuration; the deployment can be reactivated with the same id.
max_scale_down_rate is bounded to 1-50; out-of-range values are rejected rather than clamped.
GET /v1/models is documented as beta - field names may shift before general availability.
