Financial data API built to be queried by LLMs, not just humans. US equities, 30+ years of daily prices and SEC fundamentals.

The problem: every time you ask an LLM to write something with financial data, it hallucinates field names and fights the API (cough cough yfinance). We designed xfinlink to be machine-readable from the start — llms.txt, MCP server, six endpoints with consistent naming. Connect Claude or ChatGPT directly and ask questions in plain English.

Also built a proper entity resolution layer. Most providers silently merge recycled tickers into one series. We track every entity separately with exact dates. This is an institutional-grade data feature offered for free as part of the package.
