  Searched for published Grainger API rate limits and probed the only reachable Grainger API host
  (api.grainger.com) anonymously on 2026-08-28.
limit_count: 0
rate_limits: []
headers: []
note: >-
  No rate limit, quota, throttle or backoff guidance is published by Grainger anywhere reachable, and
  none could be observed at runtime: api.grainger.com answers anonymous requests with either a bare
  404 (istio-envoy, zero-length body) or a 503 ACCESS DENIED page, so no successful response carrying
  RateLimit-*, X-RateLimit-* or Retry-After headers was ever returned. The EDI and cXML PunchOut
  channels are batch/session protocols provisioned per trading partner and carry no documented
  request-rate contract. An honest zero, not an omission.
