notes: >-
  Riverlane's lifecycle commitments are made on the SDK, not on the HTTP API. The SDK states its
  policy explicitly (SemVer 2.0.0 + SPEC 0 for Python/dependency support windows) and ships a dated
  changelog and tagged releases. The cloud API itself carries no published versioning policy,
  deprecation policy, Sunset/Deprecation header support, SLA or status page — those are recorded
  below as absent, and no StatusPage or Deprecation pointer is wired in apis.yml.
versioning:
  sdk:
    scheme: semver
    spec: https://semver.org/spec/v2.0.0.html
    current: 0.9.0
    released: '2026-07-09'
    pre_1_0: true
    note: >-
      Development status is declared "3 - Alpha" on PyPI and the package is pre-1.0, so breaking
      changes are permitted between minor versions.
    support_policy: SPEC 0
    support_policy_url: https://scientific-python.org/specs/spec-0000/
    python_supported: '>=3.10,<3.15'
  api:
    scheme: uri-path + client switch
    versions:
    - {version: 1, transport: graphql, path: /api/graphql, status: available}
    - {version: 2, transport: rest, path: /api/v2/, status: available, default: true}
    policy_published: false
    note: >-
      v1 and v2 coexist at the same base URL with the same token. Riverlane has published no
      statement about how long v1 will remain available.
deprecation:
  policy_url: null
  policy_published: false
  sunset_header: false
  deprecation_header: false
  note: >-
    No RFC 8594 Sunset/Deprecation header support is documented and no deprecation policy page
    exists. The riverlane/QHAL repository is publicly marked DEPRECATED, but that is a retired
    research project, not an API deprecation policy.
sla:
  url: null
  published: false
  uptime_target: null
  note: >-
    No SLA or uptime commitment is published for the Deltakit Cloud API. The docs do warn that a
    "no healthy upstream" condition can occur intermittently.
status_page: null
status_page_probes:
- {url: 'https://status.riverlane.com/', status: 'no DNS resolution'}
- {url: 'https://status.deltakit.riverlane.com/', status: 'no DNS resolution'}

deprecated_operations: []
deprecated_operations_note: >-
  Cannot be derived — Riverlane publishes no OpenAPI, so there are no operations carrying
  deprecated: true.
