description: >-
  Versioning and lifecycle posture for the Bloomberg data-workflow APIs, read from the surfaces
  Bloomberg publishes anonymously. The SDK is versioned publicly and released often; the HTTP
  contract is not versioned in public at all.
versioning:
  scheme: sdk-semver
  current: 3.26.7.1
  docs: https://bloomberg.github.io/blpapi-docs/
  note: >-
    BLPAPI SDK builds carry a four-part version (3.26.7.1) and each minor gets its own published
    reference set at bloomberg.github.io/blpapi-docs/<language>/<major.minor.patch>/. The Data
    License REST API is served under a single unversioned path prefix (/eap/) with no version
    segment, no Accept-version header documented, and no public version history.
  api_path_versioning: false
deprecation:
  policy_url: null
  sunset_header: unknown
  note: >-
    No public deprecation policy, no RFC 8594 Sunset/Deprecation header documentation, and no
    published end-of-life schedule for SDK versions. The API Library page carries only the current
    release; the "all versions" index it links (https://blpapi.bloomberg.com/all_versions.html)
    returns 404, so even the historical version list is broken in public.
  observed:

    status: 404
sla:
  url: null
  uptime_target: null
  note: >-
    No public SLA or uptime commitment. Availability terms are contractual, inside the Bloomberg
    Professional / Enterprise agreement.
status_page: null
status_page_note: >-
  No public status page. status.bloomberg.com does not resolve (NXDOMAIN). Service health for
  enterprise connectivity is surfaced inside the customer-gated Enterprise Console
  (console.blpprofessional.com), which is an Angular SPA behind login.

    url: https://data.bloomberglp.com/professional/sites/10/2017/03/BLPAPI-Core-Developer-Guide.pdf
    note: >-
      The canonical narrative documentation the API Library links is a 2017 PDF (v1.6, dated
      8/30/2016) — still served (200, 1.2MB) and still the only conceptual guide on offer.

    note: >-
      Bloomberg's own open-source HTTP wrapper for BLPAPI. Archived; last commit January 2016. It
      is the only first-party attempt at an HTTP projection of BLPAPI in public and it is dead —
      recorded so nobody mistakes it for a current contract.
