description: >-
  Amgen documents no API rate limits, because it publishes no API. There is no developer
  portal, no API reference, and therefore no published window, quota, burst allowance,
  X-RateLimit-*/RateLimit-* response header or 429 contract to record.
notes: >-
  limit_count is 0 and limits[] is deliberately empty. A prior bulk sweep (2026-05-04) carried
  a single placeholder row reading "see provider; not publicly documented"; that row described
  an absence but scored as a documented rate-limit signal, so it was removed on 2026-09-02.
