The window is 4 hours from `maintenance_start` (UTC) on `maintenance_day`. Updated August 24, 2026 ## OpenAPI ````yaml PATCH /api/v1/k8s/clusters/{cluster_id}/maintenance openapi: 3.0.3 info: title: Raff API description: > REST API for managing cloud infrastructure on Raff. ## Authentication Most endpoints require authentication via API key. Catalog endpoints under `/api/v1/public/` are open and require no authentication. ### API Key Authentication Include your API key in the `X-API-Key` header: ``` curl -H "X-API-Key: YOUR_API_KEY" https://api.rafftechnologies.com/api/v1/vms ``` ## Catalog Use the public catalog endpoints to discover available regions, OS templates, and pricing plans before creating resources: - `GET /api/v1/public/regions` — list available regions - `GET /api/v1/public/templates` — list OS templates (use the `id` as `template_id` when creating a VM) - `GET /api/v1/public/pricing/vm` — list VM pricing plans (use the `id` as `pricing_id` when creating a VM) - `GET /api/v1/public/pricing/volume` — volume storage pricing - `GET /api/v1/public/pricing/snapshot` — snapshot storage pricing - `GET /api/v1/public/pricing/backup` — backup storage pricing - `GET /api/v1/public/pricing/ip` — IP address pricing - `GET /api/v1/public/pricing/database` — managed database pricing (plans, high availability, read replicas, extra storage) - `GET /api/v1/public/pricing/kubernetes` — managed Kubernetes pricing (worker node plans, HA control plane, storage nodes) version: 1.0.0 contact: name: Raff Technologies url: https://rafftechnologies.com servers: - url: https://api.rafftechnologies.com description: Production security: - ApiKeyAuth: [] tags: - name: Catalog description: >- Discover available regions, OS templates, and pricing plans.
