The Data Behind My Analyses Is Now Open. Download the Whole Database or Query a Single Row.
Published: June 5, 2026
The analyses I've been posting these past months.. they all run on the same data. And that data is now open to everyone.
US delinquencies, private credit, life insurance, the markets piece. All off primary data, FRED, RBI, Fed, FDIC, refreshed three times a day by the same pipeline that runs the live apps.
Pull a single row, or take the whole database.. SQLite, DuckDB, Parquet, CSV. Query it live. Or point your own agent at the MCP and let it do the fetching... or wrap the API in your own.
