  Searched for published ADT API rate limits and probed api.adt.com for runtime rate-limit
  response headers. Neither could be obtained.
reconciled: false
limit_count: 0
limits: []
description: >-
  ADT publishes no rate-limit documentation, and no runtime signal could be observed:
  api.adt.com completes a TLS handshake but returns zero bytes to any anonymous HTTP
  request, so no X-RateLimit-*, RateLimit-* or Retry-After header could be read from a live
  response. An honest zero.
notes: >-
  Supersedes the 2026-05-04 bulk-sweep scaffold, which asserted a "Partner-scoped limit"
  and throttled/serviceUnavailable response codes of 429/503. Those codes were assumed, not
  observed on any ADT response, and are removed.
