  Market Data is metered on a daily (or per-minute, on higher tiers) API-credit
  model rather than a flat per-endpoint fee. Every successful request costs at
  least one credit, and multi-symbol responses - bulk quotes, bulk candles, and
  options chains - consume one credit per symbol returned, so a single SPX
  option-chain call can cost thousands of credits. New users get a 30-day trial
  (no credit card) that rolls into a Free Forever plan (100 requests/day). Paid
  plans - Starter, Trader, Prime, and Quant - raise or remove the daily cap.
  Real-time data is the one feature excluded from free trials due to exchange
  regulations for non-professional users. Prices below reflect published rates
  and should be reconciled against the live pricing page.
notes: >-
  Starter and Trader advertise a lower effective monthly rate when billed
  annually versus month-to-month. Prime and Quant remove the daily credit cap
  and instead apply a high per-minute credit ceiling. Verify current tiers,
  prices, and credit allowances on the Market Data pricing page during
  reconciliation.
