  note: >-
    Every REST surface carries a major version in the path — /app/api/v1 for Xpansiv
    Connect and Managed Solutions, /fileRegistry/v1, /meter/v1, /reporting/v1,
    /resource/v1 and /transfer/v1 for Optimal Outcomes, /clientapi with /api/... for the
    NAR and TIGR registries. Only v1 exists publicly; no v2 or /v0 surface was found.
  spec_versions:
  - api: Xpansiv Connect API
    info_version: 1.0.0-beta
    openapi: 3.0.1

      info.version.
  - api: Xpansiv Managed Solutions API
    info_version: '1.10'
    openapi: 3.0.0
  - api: APX Power Markets File Registry API
    info_version: 1.1.49

      visible evidence of iterative release numbering.

    openapi: 3.0.1

deprecation:

  note: >-
    No operation, parameter or schema in any of the eleven descriptions carries
    deprecated: true, and no deprecation or sunset policy page exists on the developer
    portal. No `Deprecation` pointer is emitted — there is no policy to point at.

  note: >-
    No dated developer changelog. The one dated change record Xpansiv publishes is the
    inline history comment inside the APXScheduleAPI XSD at
    https://developer.xpansiv.com/developer-portal/xpansiv-power/rest_api/xsds, whose
    most recent entries are "Feb 21, 2025 Removed reference to MISO and PJM in the
    <Region> enumeration", "Feb 21, 2025 Added AS-Only in the <TransactionType>
    enumeration" and "May 6, 2026 Added 4 new products for CAISO DAME market change".
    That is a schema comment, not a changelog, and it covers only the power-markets file
    contracts. No `ChangeLog` pointer is emitted.

      Redirects to https://www.atlassian.com/software/statuspage — the vendor's own
      marketing page, i.e. the subdomain is unclaimed. NOT an Xpansiv status page.
  note: >-
    No public status or uptime page. The nearest operational signals a client has are the
    two ping health endpoints published in the contracts — GET /api/system/ping on the
    NAR and TIGR registry client APIs and GET /optimal/v1/system/ping on the Optimal
    System API — both of which require credentials. No `StatusPage` pointer is emitted.
sla:
  published: false
  note: No public SLA. https://www.xpansiv.com/general-terms-of-use governs use of the
    website and services; no availability commitment is published for the APIs.
