Use clusterId to filter to one cluster; without it, records are emitted per cluster per bucket. Each record includes GPU compute, disk, inter-node networking, and total amounts. Instant Clusters are GPU-only, so no CPU cost component is returned. ## OpenAPI ````yaml get /v2/billing/clusters openapi: 3.1.0 info: title: Runpod REST API version: 2.0.0 description: Runpod public REST API — v2 servers: - url: https://api.runpod.io description: Runpod API v2 production server security: - bearerAuth: [] tags: - name: Pods description: GPU and CPU pod lifecycle, configuration, actions, and log streaming. - name: Serverless description: >- Serverless endpoint lifecycle, worker visibility, releases, and worker log streaming. - name: Templates description: Reusable pod and endpoint configuration templates. - name: Network Volumes description: Persistent network storage volumes for workloads. - name: Registries description: Container registry credentials used to pull private images. - name: Catalog description: Available GPU, CPU, and data center catalog metadata. - name: Billing description: Billing history and usage cost records across resource types. paths: /v2/billing/clusters: get: tags: - Billing summary: Get Instant Cluster billing history description: > Returns Instant Cluster billing history for the authenticated user, split into time buckets by startTime/endTime with bucketSize or by lastN recent buckets.
