The best Unusual Whales API alternative
By Faizan Ahmad. Updated .
The Tradytics API comes with Pro at $69 a month, and Pro includes the full app. Unusual Whales sells its API separately: $99 a month for a 1-year lookback and 25,000 requests a month, $150 for 2 years, and $375 for WebSocket. The Tradytics API allows 300 calls a minute and 50,000 a day over one dataset: every options flow order since March 31, 2025 (19.96 million), the ranked dark pool (24.4 million prints since October 2024, each ranked against the stock's own 12 months), dealer gamma, delta, vanna and charm, Kalshi and Polymarket with the settled archive of 5.95 million markets, Signals and the AI Fund's trades, with an MCP server for Claude, ChatGPT and Cursor. Unusual Whales' API has Polymarket only, and its $99 plan leaves out GEX and prediction markets. Unusual Whales leads on a 100+ tool MCP, WebSocket streaming, CME futures and Kafka.

What the Tradytics API covers
- Options flow and its history. The options flow API returns orders, not raw fills: a sweep across 12 exchanges comes back once, with its side, about 58,000 orders a session across about 1,150 underlyings.
- Ranked dark pool. The dark pool data API returns every block print with its rank against the stock's last 12 months, and the levels where the dollars concentrated, across 14,147 tickers.
- Prediction markets. The prediction market data API serves Kalshi and Polymarket, live questions and the settled archive.
- Dealer exposure and the options market. Gamma, delta, vanna and charm by strike and expiry, 0DTE gamma for SPY, SPX and QQQ, open interest and market sentiment.
- Signals, the AI Fund, the scanner and research. Live Signals, every trade of the Tradytics AI Fund, the 120-signal scanner, quotes and bars.
- MCP. The MCP server at tradytics.com/mcp gives Claude, ChatGPT, Cursor and other agents the same data as tools (15 today). See the Tradytics API and MCP server and the API docs.
Because it is one dataset, one key reads a stock's flow, its dark pool ranks and its dealer gamma for the same day, next to the market's odds. The same data runs the backtester in the app.
