  The Cboe LiveVol All Access API meters usage with a points system: each
  request consumes points, and subscriptions carry a daily (trial) or monthly
  (paid tier) points allowance. 429 is returned both when request frequency
  exceeds rate limits and when the points allowance is exhausted. Tier 1-4
  customers monitor consumption in the API Statistics dashboard on Cboe
  DataShop; paid tiers can buy overage per point.
