Stock data,
where you already work.

Connect an AI assistant over MCP, pull prices into a spreadsheet, or call the REST API from Python and JavaScript.

Claude

Connect Claude to stock market data with the OHLC MCP server: add a custom connector, sign in with OAuth, and ask for prices, fundamentals and API help.

ChatGPT

Use stock market data in ChatGPT: add the OHLC MCP server as a developer-mode app, sign in with OAuth, or give ChatGPT /llms-full.txt for coding help.

Excel

Load stock prices into Excel with Power Query or WEBSERVICE: CSV from the OHLC API, the key in a header, refreshable daily bars and a latest-close formula.

Google Sheets

Pull stock prices into Google Sheets with IMPORTDATA and the OHLC API's CSV output, or keep your key private in a shared sheet with an Apps Script function.

Python

Use the OHLC stock market data API from Python: requests or urllib, cursor pagination, a pandas DataFrame of daily bars, and error handling with Retry-After.

JavaScript

Call the OHLC stock market data API from Node.js or TypeScript with fetch: typed responses, cursor pagination, a server-side proxy and WebSocket quotes.

A little JSON.
A lot of possibility.
