Hi Product Hunt! We built FinzData because backtests on today's stock lists quietly drop every company that failed, and the results come out too good. We measured it: on the top 3,000 US stocks, 12-1 momentum returned 6.89% a year with delisted stocks included and 10.55% without them. Same strategy, same years.
FinzData gives AI assistants and quants the whole market, remembered: 16,000+ US stocks since 2000 with delisted names, 5,100+ ETFs, tick data, 139 futures markets, options chains and gamma (GEX), crypto, FX, 123 indexes, COT since 1986, 13F, insider trades, short interest, fundamentals as filed, 22,700+ macro series with every vintage, congressional trades, election spending, margin debt and shipping chokepoints. Every data call takes an as_of date, so you see only what was public that day. Backtests and a survivorship audit run on our servers, and one MCP server works in Claude, ChatGPT and Cursor: https://api.finzdata.com/mcp
