note: '4DBIM documents no rate limits because it documents no API. The 4DBIM Cloud product page
  markets an "API开放平台" (API open platform) as a capability, but no reference, specification,
  quota table or response-header contract accompanies it, and no API host resolves under 4dbim.ren.
  There is therefore no runtime signal for an agent to read. No RateLimits pointer is emitted —
  this file records an absence, not a published limit.'
