What yfinance is

A free, open-source Python library (Apache 2.0) you install with pip install yfinance. It covers prices, statements, news and a screener.

Its own README says: "yfinance is not affiliated, endorsed, or vetted by Yahoo, Inc." and is "intended for research and educational purposes", and: "Remember - the Yahoo! finance API is intended for personal use only."

It calls Yahoo's unofficial endpoints, so Yahoo's terms apply to the data.

  • Finks

    Best for: AI agents that search in plain English and need the passage that answers, with its source.

    Finks is a search API built for AI agents. Your agent searches in plain English and gets back the results that answer it, each linked to its source. Today that covers news, SEC filings and earnings call transcripts.

    Filing results can carry the matching passage in the filing's own words, which your agent can quote and cite. The Finks MCP server adds the same search to Claude, Cursor or any MCP-compatible client.

    For an agent that needs answers with a source, Finks is an API with a key, and every result links to its source.

    What Finks does not do

    Finks does not return stock prices, time series, technical indicators or financial statements. If your agent needs those, use Alpha Vantage or another market data API for them.
