  HTX documents rate limits per interface, applied per IP and/or per API key.
  The figures below are the cross-cutting limits confirmed from the API reference
  and support announcements; individual trading endpoints (e.g. place/cancel
  order) publish their own tighter per-endpoint limits.
scope: [per-ip, per-api-key, per-endpoint]
signaling: >-
  Exceeding a limit returns an error response (err-code too-many-requests). HTX
  does not document standardized X-RateLimit-* response headers.
