Alpaca
Stock, option, and crypto market data queries
Overview
What Alpaca does
Alpaca supplies market data, and this app makes it queryable in conversation. Stocks, options, and crypto are covered, with historical series, snapshots, quotes, and option chain detail available.
The sample questions in the record compare one stock's quarterly performance against another, request an option chain for a specific expiry, and ask when bitcoin crossed a price level during the year. Requests are phrased as market questions rather than as API calls. The record also connects the data to automated actions built on top of the analysis, with Alpaca as the developer.
What stands out
Option chain data by expiry sits next to equity and crypto pricing in one app.

Where Alpaca is listed
Alpaca is listed in the ChatGPT apps directory only. Alpaca has no connector under the same domain in the Claude directory; 392 of the 3,150 products here are on both marketplaces, and this is not one of them.
ChatGPT apps are built on MCP, and the same server can back a Claude connector, so the absence is a distribution decision rather than a technical one.
