## OpenAPI

````yaml POST /api/v1/vms/{id}/tags
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
