  Derived by search, not from a spec — TTB publishes no OpenAPI, so there are no
  securitySchemes to aggregate. The auth model is nonetheless well-defined and worth recording:
  TTB's machine-readable open data is entirely anonymous and issues no credentials of any kind,
  while its two transactional web applications are session-login only with no programmatic
  access path.

      https://www.ttb.gov/images/foia/cola_stats.xml and
      https://www.ttb.gov/images/foia/form_stats.csv both return HTTP 200 with no
      Authorization header, no cookie and no API key (probed 2026-09-01). The COLA Public
      Registry page states no registration or password is required to use it.
