Serverless

List serverless endpoint workers

Lists the active workers for a serverless endpoint.

Returns. A 200 with a ListEndpointWorkersResponse: a workers array (one entry per active worker, each carrying its id, status, and runtime details) plus a summary of worker counts grouped by status. Only currently active workers are included; scaled-down workers are not returned.

How status is determined. Each worker’s status is derived by reconciling the worker pod’s lifecycle status with the endpoint’s live job-queue view (which workers are actively serving requests). When the job-queue view is unavailable, the response degrades gracefully: the shape is unchanged, but each status and the summary counts fall back to pod lifecycle alone.

Authorizations

Authorization

string

header

required

Runpod API key authentication. Generate an API key in the Runpod console and send it in the Authorization header as Bearer <api_key>. Keys are scoped to the permissions granted when created; requests may return 403 when a valid key lacks access to the requested resource or action.

Path Parameters

string

required

Serverless endpoint identifier

Response

workers

object[]

required

Show child attributes

summary

object

required

Histogram of the returned workers by status. The per-status counts are a roll-up of the workers array, so running + idle + initializing + throttled + unhealthy == total == len(workers).

Show child attributes

endpointVersion

integer | null

The endpoint's current configuration version. A worker whose version differs is running stale config (see worker.isStale). Null if unknown.

Example:

4

List serverless endpoint releasesReturns the endpoint's release history (newest first) plus a rollout summary of how many workers are running the current version. Each release is a versioned configuration snapshot with a `diff` of what changed; build-driven releases carry a `buildId` (fetch build detail via the builds sub-routes).
