  Marketaux enforces two ceilings: a rolling 60-second rate limit signaled via
  the X-RateLimit-Limit header (429 rate_limit_reached when exceeded; the
  numeric per-minute cap is not published), and a plan-based daily usage quota
  signaled via the X-UsageLimit-Limit header (402 usage_limit_reached when
  exhausted). Daily quotas per plan are published on the pricing page.
