conformance:
  - id: rfc9457
    name: Problem Details for HTTP APIs (application/problem+json)
    conforms: false
    evidence: >-
      Errors use a flat {error, message} JSON envelope with application/json, not
      application/problem+json. See llms-api-hu.txt "Hibakódok".
  - id: oauth2
    name: OAuth 2.0
    conforms: false
    evidence: Authentication is a static bearer API key (flh_live_…), not an OAuth flow.
  - id: pagination
    name: Offset/limit pagination
    conforms: true
    evidence: >-
      GET /companies documents limit (max 100, default 25) and offset (default 0) params and a
      pagination object {total, limit, offset, hasMore}. llms-api-hu.txt "GET /companies".
domain_standard:
  - id: teaor-25
    name: TEÁOR'25 (Hungarian activity classification, national NACE Rev.2.1 derivative)
    declared: true
    evidence: >-
      Company records carry a teaorCode field, and the full four-level TEÁOR'25 classification is
      published unauthenticated as machine-readable JSON at https://felho.hu/teaor-index.json
      (probed 2026-09-18, HTTP 200, application/json). A consumer that already speaks TEÁOR'25
      integrates the industry code with no bespoke mapping.
consumed_standards:
  - id: rdap
    name: RDAP / WHOIS (domain registration data)
    note: >-
      GET /whois/{domain} wraps WHOIS/RDAP lookups. The API is a client/aggregator of RDAP, not an
      RDAP server itself, so it is recorded as a consumed standard, not a conformance claim. The
      response carries a three-valued `registered` field and a note that several registries
      (.hu/.de/.at/.eu) do not publish expiry dates.
