  Collision / Web Summit Vancouver publishes no rate limits, because it publishes no API. There is no
  developer documentation in which a limit could be stated, no base URL an agent could pace itself
  against, and no key to which a quota could attach. This is an honest zero recorded after probing
  ten hosts for a contract or discovery document on 2026-09-05, not an unchecked field. The event
  sites' robots.txt disallows /api/ on both vancouver.websummit.com and websummit.com, which this
  profile honors — no limit was observed there because no request was made there.

    None of the seven headers appeared on any response from the public marketing hosts or from
    api.websummit.com / attend.websummit.com. An agent gets no runtime signal of any kind.

    All event hosts sit behind Cloudflare, and support-vancouver.websummit.com answered a Cloudflare
    managed-challenge interstitial (HTTP 403, "Just a moment...") to an ordinary browser user agent.
    Edge bot management is therefore certainly in force, but it is an edge policy rather than a
    published API rate limit. Recorded as inference, explicitly not as a published limit.
