Massive offers a separate subscription for each major asset class, Stocks, Options, Indices, Currencies (Forex + Crypto), and Futures, plus add-on access to economic data and partner datasets. Each subscription has multiple tiers, ranging from free end-of-day data up to full real-time tick-level data.
Subscriptions are independent, so you can mix and match. A customer who only needs equities can subscribe to Stocks; one building a multi-asset platform might subscribe to Stocks, Options, Indices, Currencies, and Futures together.

Aggregate bars, trades, NBBO quotes, snapshots, technical indicators (SMA / EMA / RSI / MACD), corporate actions (dividends, splits, IPOs, ticker events), reference data, fundamentals (financial statements, ratios, short interest), and SEC filings (10-K, 13-F, 8-K, Form 3/4).
