  Nanonets returns HTTP 429 when an account exceeds its allowed concurrent request
  count. The platform documents Retry-After-style backoff handling on the
  "How to handle 429 Error?" reference page; specific per-tier quantitative
  limits are not publicly published and are governed by the consumption-based
  credit model (see plans).
