US options and equities market data: historical option contract pricing and OHLC bars, the full options reference catalogue, stock aggregates and previous closes, ticker reference data, company news and market status.
Build a correctly formatted OCC option symbol from an underlying, expiry, type and strike. Runs locally with no API call. ALWAYS use this instead of hand-writing option tickers - the strike padding is error-prone and a malformed symbol returns empty results with no error.
Get upcoming US market holidays and early closes.
Get the current market status: whether equities and options markets are open, in early hours, or in after hours. Check this before describing any price as live.
Get historical OHLCV bars for an option contract over a custom date range and interval. Note that bars only exist for intervals where qualifying trades occurred, so illiquid contracts have gaps.
Get reference details for one option contract: strike, expiry, contract type, exercise style, shares per contract and primary exchange.
Get the open, high, low and close for an option contract on a specific date.
Get the previous trading day's OHLCV bar for an option contract.
Get historical OHLCV bars for a stock over a custom date range and interval. Use this for charting and for establishing the underlying price history behind an options analysis.
Get the previous trading day's OHLCV bar for a stock.
Get reference details for a ticker: company name, description, market cap, shares outstanding, SIC industry description, homepage and branding.
Get recent news articles for a ticker, including publisher, description and sentiment insights where available.
List option contracts from the reference catalogue for an underlying. Returns contract metadata (strike, expiry, type, exercise style) but NO pricing, Greeks or open interest - use get_option_chain for those.
Search for tickers by name or symbol across stocks, options, indices, crypto and FX. Use this when the user names a company but not its ticker.
