  Live probes of https://char.gy/open-ocpi/*, https://char.gy/ocpi/cpo/* and the
  char.gy help centre, 2026-07-27
versioning:
  open_feed:
    scheme: none
    detail: >-
      No version is declared anywhere on the open data feed. GET
      /open-ocpi/versions returns 404, so the OCPI version-negotiation mechanism
      is not implemented, and the payload shape is the only contract. There is
      no version in the path, no version header and no media-type versioning.
  cpo_roaming:
    scheme: uri-path
    supported: ['2.2.1', '2.1.1']
    rejected: ['2.2']
    evidence: >-
      /ocpi/cpo/2.2.1/locations and /ocpi/cpo/2.1.1/locations return HTTP 401
      (real, credential-gated routes) while /ocpi/cpo/2.2/credentials returns
      status_code 3002 "Unsupported version" — so version support is directly
      observable without a credential.
    versions_endpoint: https://char.gy/ocpi/cpo/versions
    versions_endpoint_status: 401
deprecation:
  policy_url: null
  policy_published: false
  sunset_header: false
  detail: >-
    No deprecation policy, no RFC 8594 Sunset or Deprecation header, and no
    notice period is published for either surface. No Deprecation pointer is
    wired in apis.yml because none exists.
deprecated_operations: []
status_page:
  url: null
  published: false
  detail: >-
    status.char.gy does not resolve and https://char.gy/status returns 404. No
    uptime or incident-history page was found, so no StatusPage pointer is
    wired. Per-charge-point availability is, however, effectively self-reporting
    through the EVSE status field on /open-ocpi/locations, which regulation
    10(4) requires to be updated within 30 seconds of a change.
sla:
  url: null
  uptime_target: null
  detail: >-
    No SLA is published for either API. The statutory obligation in regulation
    10 is on data availability, not on API uptime, and char.gy makes no
    availability commitment to data consumers.
changelog:
  url: null
  published: false
  detail: >-
    No changelog, release notes or version history exists for either surface.
    The only published documentation is one Freshdesk article with no version
    and no date. Data freshness must be inferred from last_updated on each
    object and from the date_from/date_to filters.
freshness_observed:
  locations_total: 5409
  updated_since_2026_07_27: 2396
  oldest_sampled: >-
    Only 6 locations had last_updated before 2026-07-01, indicating the whole
    feed is actively rewritten rather than stale.
  tariffs_note: >-
    Of three tariff objects, the EUR and USD records were last_updated in
    October 2025 while the GBP record was updated 2026-07-23.
