This artifact previously carried a 2026-05-04 bulk-sweep placeholder asserting a 429 throttle response and a "Dealer agreement throttling" policy; neither was observed or documented, so both have been removed in favour of a measured zero. notes: >- limit_count is 0 by measurement. No X-RateLimit-*, RateLimit- (RFC 9239 draft), or Retry-After header appeared on any probed response, and no throttling status code was observed. Quote and order pacing on the wholesale desk is governed by the bilateral dealer agreement, which A-Mark does not publish — that is a real constraint, but it is not a documented API rate limit and is no longer recorded as one. limit_count: 0 limits: [] response_headers: [] exhaustion_status_code: null sources: - url: https://www.amark.com/services/ http_status: 200 note: no limits documented - url: https://portal.amark.com/.well-known/openid-configuration http_status: 200 note: no rate-limit headers on the response - url: https://trading.amark.com/v1/openapi.json http_status: 404 note: >- anonymous ASP.NET Web API response carried no rate-limit headers maintainers: - FN: Kin Lane email: kin@apievangelist.com
