  https://docs.paubox.com/email-api, https://status.paubox.com/,
  https://www.paubox.com/pricing/paubox-email-api, and the three OpenAPI documents in
  openapi/.
description: >-
  Versioning, deprecation, status and support posture for the Paubox API surface. Paubox
  runs a live status page and states an uptime commitment on its pricing page, but
  publishes no deprecation policy, no changelog and no Sunset/Deprecation header contract.

versioning:
  scheme: url-path
  current: v1
  bases:
    - https://api.paubox.com/v1/email
    - https://api.paubox.com/v1/marketing
    - https://api.paubox.com/v1/forms
  spec_info_versions:
    paubox-email-api-openapi.yaml: 1.0.0
    paubox-marketing-api-openapi.yaml: 1.0.0
    paubox-forms-api-openapi.yaml: 1.0.0
  header_versioning: false
  note: >-
    Only one API version has ever been published. There is no v0 or v2, so no migration
    precedent exists to reason from.

deprecation:
  policy_published: false
  policy_url: null
  sunset_header: false
  deprecation_header: false
  rfc8594: false
  deprecated_operations: []
  evidence: >-
    No operation in any of the three OpenAPI documents carries `deprecated: true`. No
    deprecation, sunset, EOL or migration-policy page appears in the published
    https://docs.paubox.com/llms.txt index, and no such page was found on
    www.paubox.com.

change_log:
  published: false
  url: null
  evidence: >-
    https://docs.paubox.com/changelog returns 404 and no changelog, release-notes or
    what's-new entry appears in the published llms.txt documentation index. Release
    history is discoverable only per-SDK from the GitHub repositories under
    https://github.com/Paubox and from the package registries (see
    packages/paubox-packages.yml).

  published: true
  url: https://status.paubox.com/

    Stated on the pricing page as part of the Paubox Email Suite Standard plan feature
    list and repeated as "99.99% uptime" against the U.S. data-center infrastructure
    claim. No separate machine-readable SLA document or credit schedule is published.
