api: REALTORS M1 Gateway External API
summary: >-
  NAR runs the M1 Gateway as a partner integration surface, not as a productised developer platform, and
  the lifecycle signals reflect that: there is a stated version (v1) with no version segment in any path,
  no published deprecation policy, no Sunset or Deprecation header support, no SLA, no status page and no
  changelog. The one lifecycle event NAR does publish is the platform-level one - M1 replaces the legacy
  NRDS system, and NAR lists "API Transitions" among the M1 features still to come. Change communication
  runs through association-executive channels and partner support rather than through a developer-facing
  release feed.
versioning:
  scheme: none-in-path
  current: v1
  evidence: 'Swagger 2.0 info.version = "v1"; no version segment in any of the 64 paths.'

  docs: null
deprecation:
  policy_url: null
  sunset_header: false
  deprecation_header: false
  deprecated_operations: []
  note: >-
    No operation in the published Swagger document carries deprecated: true, and no deprecation or sunset
    policy is published on any NAR host.
predecessor:
  system: NRDS (National REALTOR Database System)
  status: being replaced by REALTORS M1
  evidence: >-
    NAR's M1 page states M1 replaces the current NRDS system and lists "API Transitions" among upcoming
    features, alongside Association Portal, Committee Data Sharing, Transaction Lookup and AI
    Applications.
sla:
  url: null
  uptime_target: null
status_page: null
status_page_note: >-
  No status page exists on any NAR-controlled host - status.nar.realtor does not resolve and the M1
  Gateway host answers 401 at every path.
changelog: null
changelog_note: >-
  No changelog, release notes or version history is published for the M1 Gateway API. The supplemental
  docs repository (created 2026-07-08) carries no CHANGELOG and no releases; the Swagger and Postman files
  are the only revision signal.
