  statement: >-
    "No key and no sign-up." — https://planomy.net/data/. Both endpoints are static JSON files served
    anonymously over HTTPS; there is no credential of any kind to obtain, present, rotate or revoke.

verified:
  - check: anonymous GET of https://planomy.net/tax-data/2026.json

  - check: OpenAPI securitySchemes
    result: >-
      empty — openapi/planomy-tax-data-openapi.yml declares no securitySchemes and sets `security: []`
      on both operations, which is the accurate machine-readable statement of an open API.
notes:
  - >-
    Keyless is a deliberate posture, not an omission: the underlying figures are US-federal
    public-domain data and the licence statement invites reuse.
  - >-
    There is a separate, unrelated account system for the Planomy planner application itself
    (optional sign-in for cloud sync and Plus billing, /app/). It does not gate the data endpoints and
    exposes no documented API.
  - >-
    Because there is no credential, an agent needs no secret handling for this API — the only client
    concerns are caching (ETag / If-None-Match) and polite request volume. See
    conventions/planomy-tax-data-conventions.yml.
