• MCP tools: 30 tools cover every endpoint, one per kind of question. All of them only read.
• Libraries: Official clients for Python and JavaScript: one method per endpoint, retries on rate limits, paging and streaming built in. No dependencies.
• API keys: Send your API key in the URL as the apiKey query parameter.
• Rate limits: The API is included with Pro. Each key gets 300 calls a minute and 50,000 a day.
• Errors: A failed call answers a 4xx or 5xx status with the same JSON shape every time.
• Pagination: Long lists come a page at a time, newest first.
• Time and history: Every endpoint reads time the same way.
• Data conventions: What the numbers and fields mean across every endpoint.
• Options flow: Every options print of $25K+ as it happens and back to 2025-03-31, with side, sweep or block, opening and outcome, and the flow summed by time, name, strike and contract.
• Options contracts: Every listed contract with quotes, greeks and IV, the market-wide contract screener, one contract's bars and open interest by strike or expiry.
• Dealer positioning: Dealer gamma, delta, vanna and charm by strike or expiry for about 2,500 stocks, ETFs and indices, every 5 minutes of the session, at any moment since 2026-11-06, and 18 months of daily totals.

• Stocks: Live quotes, chart bars down to the second, the whole market in one call, technicals, short data and corporate actions for every US stock.
• Fundamentals: Every US filer's income statements, balance sheets and cash flow since 2009, built from its own filings the day they are filed, ratios at the price now or any close, and what analysts expect, report by report.
• Filings: Every SEC filing of the last three years and each new one seconds after EDGAR accepts it, with 10-K, 10-Q and 8-K sections as text and full-text search.
• Disclosures: Insider trades, institutional holdings, activist stakes and Congress trades.
• KPIs: The operating numbers that move stocks: deliveries, subscribers, same-store sales, nights booked, store counts, and weekly numbers published on the web. Every value comes with its source and the line it was read from, and each reported value is confirmed by a second, independent read of its filing before it is served.

• Insights: What the market did and why, and why each stock is moving.
• Probabilities: Every live finance question on Kalshi and Polymarket, each outcome's chance through time, the S&P 500 outlook and the settled archive since 2021.

• Symbols: Every US stock, fund and index Tradytics tracks, and each one's profile.
