Address	`https://api.hanzo.ai/v1/compute/clusters/{clusterId}/pools/{poolId}/scale`
Method	`POST`
Operation	`scaleNodePool`
Auth	`Authorization: Bearer $HANZO_API_KEY`

Resizes a node pool to an absolute node count and returns the pool as Visor reports it after the change.

Request

6 fields, body application/json (required).

Field	In	Type	Required	Description
`clusterId`	path	string	yes	ClusterID is the cluster holding the pool, from the URL path.
`poolId`	path	string	yes	PoolID is the pool to resize, from the URL path — the `poolId` a cluster read reports for it.
`clusterId`	body	string	—	ClusterID is the cluster holding the pool, from the URL path.
`count`	body	integer (int64)	—	Count is the node count to scale TO — an absolute target, not a delta, and never negative.
`poolId`	body	string	—	PoolID is the pool to resize, from the URL path — the `poolId` a cluster read reports for it.
`provider`	body	string	—	Provider is the cloud the cluster lives on.

Response

Status	Body	Meaning
`200`	compute.nodePoolView	ok
`default`	problem-details	refused

200 body — 7 fields.

Field	In	Type	Always	Description
`autoScale`	body	boolean	—	AutoScale reports whether the provider's cluster autoscaler owns this pool's size, moving Count between MinNodes and MaxNodes as workloads demand.
`count`	body	integer (int64)	—	Count is how many nodes the pool has right now.
`maxNodes`	body	integer (int64)	—	MaxNodes is the ceiling the autoscaler will not grow the pool past, and so the bound on what this pool can cost.
`minNodes`	body	integer (int64)	—	MinNodes is the floor the autoscaler will not shrink the pool below.
`name`	body	string	—	Name is the pool's name as the provider knows it.
`poolId`	body	string	—	PoolID is the provider's id for the pool — the value the scale and delete routes address it by.
`size`	body	string	—	Size is the provider size slug every node in the pool runs at ("s-4vcpu-8gb", "gpu-h100x8-640gb").

Failure carries the platform error shape — see Errors.
