About
Market Data provides a REST API and Google Sheets add-on for U.S. market data, including stocks, options, ETFs, and mutual funds. The service exposes real-time and delayed quotes, historical candlesticks, option chains, Greeks, implied volatility, and spreadsheet formulas for pulling data into Sheets.
The free offering includes 100 Sheets formulas, 100 daily API credits, standard API endpoints, 1 year of historical data, 24-hour delayed stock data, and 24-hour delayed options data. The pricing page also states that the free plan is for internal use and that real-time stock and options data are reserved for paid plans.

Free Tier Value
This free tier is genuinely usable but tightly capped: it includes a 30-day no-credit-card trial and then drops to a perpetual free plan with 100 formulas and 100 API credits per day, plus delayed market data and one year of history. Compared with the cheapest paid Starter plan at $12/month, it looks worth about one Starter month for a small user, but the low daily limits and delayed access keep it well below paid-plan parity.
