  live probes
note: >-
  The FCA operates its APIs as free public utilities and publishes no lifecycle
  commitments of any kind. Every negative below was probed, not assumed.
versioning:
- api: FCA Financial Services Register API
  scheme: uri-path
  current: V0.1
  policy_url: null
  note: >-
    V0.1 has been the only version segment since the API was introduced. No
    version policy, no version-negotiation header, no announced successor.
- api: FCA Data Publication API (FIRDS / FITRS)
  scheme: none
  current: null
  note: The index name is the resource; there is no version segment.
deprecation:
  policy_url: null
  sunset_header: false
  deprecation_header: false
  note: >-
    No deprecation policy, no RFC 8594 Sunset/Deprecation header support, and no
    deprecated operations are documented or observable. No Deprecation pointer is
    wired in apis.yml because the FCA publishes no such policy.
sla:
  url: null
  uptime_target: null
  present: false
  quote: >-
    "As the API is a free service, we do not offer any service-level agreements
    (SLAs) or guarantees for uptime or issue resolution."

  - url: https://www.fca.org.uk/firms/systems-status
    status: '404'
  note: >-
    The FCA has no public status page. System availability is communicated to
    signed-in firms inside the My FCA portal, not publicly. No StatusPage pointer
    is wired in apis.yml.
changelog:
  present: false
  note: >-
    No API changelog or release notes. The FS Register web page carries a dated
    "Page updates" list (last entry 13/02/2026), but that tracks edits to the
    web page, not to the API contract. The FIRDS technical specification is
    dated July 2020 and carries no revision history.
support:
  contact: https://www.fca.org.uk/contact
  note: >-
    General FCA contact routes only; there is no developer support channel,
    community forum or issue tracker for either API.
