description: >-
  ABM Industries publishes no rate limits for ABM Connect. There is no developer portal, no API
  reference and no limits page anywhere in ABM's own 594-entry llms.txt site index.
response_headers:
  observed: []
  note: >-
    No X-RateLimit-*, RateLimit-* or Retry-After header appeared on any unauthenticated response
    from https://connectapi.abm.com/ or https://abm-apim.azure-api.net/. ABM fronts its APIs with
    Azure API Management, which can enforce quota and rate-limit policies, but whether ABM
    applies any — and what it would return — cannot be established without credentials.
responseCodes:
  throttled: unknown
  note: 429 was never observed; the gateway returned 401/404/500 on probe.
notes: >-
  Upgraded 2026-08-29 from a 2026-05-04 bulk-sweep placeholder (method: generated) which asserted
  a named "ABM Connect throttling" policy and a 429 response code that no evidence supports. An
  honest zero replaces it.
