  Spot/Futures OpenAPI in openapi/.

  Versioning, deprecation, and availability posture across Kraken's API surfaces.
  Kraken versions primarily by URI path (Spot endpoints under /0/, Futures under
  /api/v3) and by protocol generation (Spot WebSocket v1 legacy vs v2). Kraken
  does not implement RFC 8594 Sunset/Deprecation response headers; deprecations
  are announced via blog/support and legacy surfaces are kept running.
versioning:
  spot_rest:
    scheme: uri-path
    current: '/0/'
    base: https://api.kraken.com
  futures_rest:
    scheme: uri-path
    current: v3
    base: https://futures.kraken.com/derivatives/api/v3
  spot_websocket:
    scheme: protocol-generation
    current: v2
    base: wss://ws.kraken.com/v2
    legacy: v1 (wss://ws.kraken.com) — still operational, v2 recommended for new work
  docs: https://docs.kraken.com/api/
deprecation:
  policy_url: null
  sunset_header: false
  notes: >-
    No RFC 8594 Sunset/Deprecation headers. Legacy surfaces (Spot WebSocket v1,
    Crypto Facilities Futures v3 clients) remain operational; migration guidance
    is published via the docs and blog rather than machine-readable headers.
legacy_surfaces:
  - name: Kraken Spot WebSocket API v1
    superseded_by: Kraken Spot WebSocket API v2
    status: operational
    evidence: apis.yml — "Continues to operate alongside v2 but v2 is the recommended path."
  - name: Crypto Facilities REST v3 / WebSocket v1 clients
    context: Kraken Futures (formerly Crypto Facilities); example clients still published.
sla:
  url: null
  public_uptime_target: null
  notes: Kraken publishes no numeric public API uptime SLA; institutional commitments are handled per agreement.
