description: Versioning and lifecycle facts as published. No deprecation policy, no Sunset/Deprecation header support,
  no SLA and no status page were found; those are recorded as absent, so no StatusPage or Deprecation pointer is
  emitted.
versioning:
  scheme: none-in-path
  current:
    openapi_info_version: 3.0.0
    x402_services_spec_version: 2.1.0
    agent_card_version: 1.1.0
    x402_manifest: x402-2.12
    a2a_protocol: 0.3.0
    ap2: '0.1'
    mpp: '1.0'
  path_versions:
  - /a2a/v1
  - /ap2/v1/merchant
  note: REST service paths (/x402/<service>, /api/...) carry no version segment; only the A2A and AP2 endpoints
    are versioned.
deprecation:
  policy_url: null
  sunset_header: false
  deprecation_header: false
  note: 'No deprecated: true operation in either spec; no policy page found (no /changelog, /deprecations or /roadmap
    route in the SPA bundle).'
sla:
  url: null
  uptime_target: null
  note: No SLA published. maxTimeoutSeconds 60 in the x402 challenge is a payment validity window, not an SLA.
status_page: null
status_page_note: 'status.coinrailz.com has no DNS record; https://coinrailz.com/x402/payment-status is a payment
  lookup endpoint, not a status page; the Cloudflare gateway root reports {status: healthy} for itself only.'
changelog:
  url: null
  note: 'No dated changelog. llms.txt carries "Last updated: 2026-09-16"; openapi.json and pricing.json carry updated
    2026-09-19. The coinrailz-mcp PyPI metadata points its Changelog at https://github.com/tdnupe3/mcp-server-coinrailz/releases.'
