versioning:
  scheme: uri-path + semver
  current: v2
  current_spec_version: 2.1.1
  released: '2021-06-23'
  base: https://trk.mtrl.me/v2
  registry: https://app.swaggerhub.com/apis/metrilo/api/2.1.1
  note: >-
    Two version axes. The callable path carries a major version (/v2); the
    specification carries a semver revision (2.1.1) published to Metrilo's own
    SwaggerHub org. Four revisions exist: 1.0.0 (2020-05-22), 2.0.0
    (2020-08-03), 2.0.1 (2021-06-02), 2.1.1 (2021-06-23). No 2.1.0 was ever
    published. Full diffs in changelog/metrilo-changelog.yml.
  spec_servers_defect: >-
    The current specification declares servers[] as https://trk.mtrl.me with no
    /v2 segment, contradicting every published example and the real base URL.
    Corrected in overlays/metrilo-tracking-api-overlay.yaml, not by editing the
    verbatim spec.
deprecation:
  policy_url: null
  sunset_header: false
  deprecation_header: false
  note: >-
    No published deprecation policy and no RFC 8594 Sunset/Deprecation header
    support. Metrilo has nevertheless retired things without one, which is
    exactly what a policy would have covered:
  observed_retirements:
    - what: API v1
      evidence: >-
        The developer guide still says "If you have integrated with the previous
        version of our API, the guide has been moved here" and links api_v1.md —
        that file returns 404. The v1 migration guide has been deleted while the
        link that promises it remains live.
      checked_status: 404
    - what: 'Legacy ingestion host: track.metrilo.com'
      evidence: >-
        Published as the production server in specification 2.0.1 (2021-06-02),
        replaced by trk.mtrl.me in 2.1.1 three weeks later. track.metrilo.com no
        longer resolves in DNS (probed 2026-08-13). No sunset notice was issued
        and the retired host is still readable in the 2.0.1 spec SwaggerHub
        continues to serve.
      checked_status: 0
sla:
  url: null
  uptime_target: null
  published: false
status_page: null
status_page_note: >-
  No status page. status.metrilo.com does not resolve and /status on the
  marketing site returns 404. No third-party status provider (Statuspage,
  Instatus, Better Stack) is referenced anywhere in the docs.

  assessment: >-
    Frozen but live. The contract has not moved in five years, the developer
    guide's last commit is the same day as the final spec revision, and the
    only client library released since is the Magento 2 extension in 2023.
    The endpoint itself is healthy — an unauthenticated POST to
    https://trk.mtrl.me/v2/customer returns 401, so the service is running and
    enforcing auth. Metrilo is still sold at published prices (see
    plans/metrilo-plans-pricing.yml). Read this as a maintained,
    feature-complete integration surface, not an abandoned one — but do not
    expect new capability.
broken_surfaces:
  - surface: Marketing blog
    url: https://www.metrilo.com/blog
    status: 500
    detail: >-
      The entire WordPress blog returns HTTP 500 from the Apache/2.4.29 origin
      behind Cloudflare — the index, /blog/page/1, /blog/sitemap_index.xml and
      individual posts all fail identically. robots.txt still advertises
      https://www.metrilo.com/blog/sitemap_index.xml, which also 500s. The Blog
      pointer has been removed from apis.yml because the surface is down.
