description: >-
  Altus Group publishes no rate limits for the ARGUS API. No public API reference exists,
  so no documented quota, window, burst ceiling or exhaustion status code could be read.
  No rate-limit response headers could be observed either: every reachable ARGUS service
  endpoint answers anonymous requests with HTTP 403 "Missing Authentication Token" before
  any limit is applied.
headers:
  limit: null
  remaining: null
  reset: null
  retryAfter: null
  policy: null
  observed: false
  note: >-
    Not observed. Anonymous probes of the ARGUS Intelligence Platform service prefixes
    (core-service-v1, backend-v1, stewardship-v1, mdmapisvc-v1, derived_domains-v1,
    stress-testing-v1 on platform.altusintelligence.com) return 403 from the fronting AWS
    API Gateway with no RateLimit-* or X-RateLimit-* headers.

  REPLACES A FABRICATED SCAFFOLD. The previous version of this file, written by the bulk
  sweep dated 2026-05-04 and carrying method: generated, asserted 10/100/1000 requests per
  minute across invented free, professional and enterprise tiers, plus X-RateLimit-* header
  names the API has never been observed to send. None of it is published by Altus Group. It
  has been removed rather than left in place; see roadmap#35.
