  Versioning, deprecation, and operational-transparency posture for Legend's
  API. Legend publishes no versioning policy, no deprecation policy, no SLA,
  and no status page — each absence below is a probed negative result, not an
  unchecked field. Because none of these surfaces exist, no `StatusPage` or
  `Deprecation` pointer is wired into apis.yml.
versioning:
  scheme: none
  documented: false
  current: null
  detail: >-
    API paths carry no version segment and no version request header is
    documented. The service reports an internal package version
    (`@legend/hl-node` 0.1.0) in its root document and a per-deploy `gitSha`
    on GET /health — build identifiers, not a consumer version contract.
  build_identifier:
    endpoint: GET /health
    field: gitSha
    observed: 8d5b251
deprecation:
  policy_url: null
  documented: false
  sunset_header: false
  detail: >-
    No deprecation policy, no RFC 8594 Sunset/Deprecation header support
    documented or observed. Note that `type: meta` marks individual markets
    with `isDelisted: true` — this is asset delisting on the underlying
    Hyperliquid venue, not API deprecation.
sla:
  url: null
  uptime_target: null
  documented: false
status_page:
  url: null
  probed:
  - {url: 'https://status.legend.trade', status: 404}
  - {url: 'https://www.legend.trade/status', status: 404}
  detail: >-
    No public status page. GET /health is the only live health signal, and it
    exposes per-dependency checks (hlVisor, postgres) with latency.
changelog:
  url: null
  documented: false
  detail: No dated changelog or release-notes surface was found on the site or docs.

    Legend's execution venue and the upstream whose API shape Legend mirrors.
    Legend's own availability and market coverage track Hyperliquid's.
