# 2026-08-28: this file previously carried a bulk-sweep SCAFFOLD (free 10/min, pro 100/min,
# enterprise 1000/min) that Zillow Group has never published. Those numbers were fabricated
# and have been removed. Every one of the seventeen API pages on
# https://www.zillowgroup.com/developers/ was read on 2026-08-28; not one states a quota, a
# window, a burst ceiling, a 429 behaviour or a rate-limit response header.

  Published rate limits for the Zillow Group API surface. There are none. Zillow Group
  documents no quota, no window, no burst, no exhaustion status code and no rate-limit
  response headers on any of the seventeen APIs listed on its developer portal — which means
  a client cannot size an integration, and an agent has no runtime signal to back off on.

      States capacity as marketing prose — "respond to millions of quotes per hour" — with no
      per-client limit, window or header. Deliberately not recorded as a limit.

    note: Webhook delivery API; no limits and no retry policy stated.
subsidiary_limits_note: >-
  The only published rate limit reachable from this portal belongs to a subsidiary: the dotloop
  Public API v2 documents 100 requests per minute per client application per user, a 429 on
  exhaustion, and X-RateLimit-Limit / X-RateLimit-Remaining / X-RateLimit-Reset response
  headers. That is dotloop's contract, recorded in all/dotloop, and is deliberately NOT counted
  as a Zillow Group limit here.
