versioning:
  scheme: uri-path
  current: v1
  docs: https://www.stannp.com/us/direct-mail-api/guide
  history: >-
    v1 is the only version Stannp has ever published on the current API hosts.
    No v0 or v2 is documented and no version-negotiation header exists.
  regional_hosts:
    - url: https://api-eu1.stannp.com/v1
      region: EU / UK
    - url: https://api-us1.stannp.com/v1
      region: US / CA
  note: >-
    Region is selected by HOST rather than by version or parameter. A key issued
    in one region does not authenticate against the other.
deprecation:
  policy_url: null
  policy_published: false
  sunset_header: false
  deprecation_header: false
  deprecated_operations: []
  note: >-
    No deprecation or sunset policy is published anywhere on stannp.com, and no
    RFC 8594 Sunset/Deprecation header is documented. Searched the API guide,
    every /us/direct-mail-api/* reference page, /us/terms-of-service and the
    knowledge base. No operation in openapi/ carries `deprecated: true`. Recorded
    as an honest absence — no `Deprecation` pointer is wired in apis.yml.
changelog:
  published: false
  probed:
    - url: https://www.stannp.com/us/direct-mail-api/changelog

    - url: https://knowledge.stannp.com/us/changelog
      status: 404
  note: >-
    No dated API changelog or release-notes page exists. The company blog
    (https://go.stannp.com/en-us/blogs) is marketing content about direct mail,
    not API release notes. No `ChangeLog` pointer is wired.
status_page:
  url: https://status.stannp.com/
  status: 200
  name: Stannp Service
  features:
    - live service status
    - 90-day uptime calendar
    - overall uptime for last 24 hours / 7 / 30 / 90 days
    - incident history
    - email subscription to status updates
  machine_readable: false
  machine_readable_note: >-
    Not a Statuspage.io-hosted page — https://status.stannp.com/api/v2/summary.json
    returns 404, so there is no JSON status feed an agent can poll. Status is
    rendered client-side for humans only.
  linked_from: >-
    The site footer, as "Service status monitor", on every stannp.com page.
sla:
  url: https://www.stannp.com/us/detailed-pricing
  uptime_target: null
  note: >-
    Stannp publishes no API uptime SLA. It does publish a PRODUCTION SLA — a
    "24-hour production SLA" included on every subscription tier, which is a
    commitment about printing and mailing turnaround, not about API
    availability. Recorded distinctly so the two are not conflated.

  api_integration_team: >-
    Stannp advertises a dedicated API integration team available on paid tiers
    (https://www.stannp.com/us/developer-tools).
roadmap:
  public: false
  note: >-
    No public roadmap. A "Product strategy group membership" is listed as a
    higher-tier subscription entitlement on
    https://www.stannp.com/us/detailed-pricing — roadmap input is a paid
    entitlement, not a published artifact. No `Roadmap` pointer is wired.
sdk_currency:
  note: >-
    The three first-party SDKs were last released in 2017 (Go, C#) and 2022
    (PHP), while the documented API surface now includes SMS, Selections, Files,
    Reporting, Addresses, QR/PDF tools and idempotency keys. See
    packages/stannp-packages.yml.
