  No rate limits are documented. 4D Bios has no developer portal, no API reference and no public
  documentation for the "4D Bios Open Platform API" it markets on its solutions page, so there is
  nothing published about quotas, windows, burst behaviour, RateLimit-* / X-RateLimit-* response
  headers, Retry-After, or the status code returned on exhaustion. Nothing could be observed on a
  live response either: the Open Platform and IoT consoles are login-gated single-page applications
  and api.4d-bios.com does not answer TCP from the probe point.
