FinzData

Built for AI, quants, data scientists and financial analysts who backtest. Clean data. Real insights. Real alpha.

Market data for every open model

Give Qwen, Kimi, GLM, DeepSeek, Llama, gpt-oss, Gemma, MiniMax and Mistral point-in-time market data, macro vintages and server-side backtests through plain function calling. Your model fetches real numbers, cites the dataset, and never has to guess.

No API key needed to start

Install and ask: your model gets FinzData's free AI preview (the last 6 months of data) with no account and no FinzData key. For more, a free API key (email only) at finzdata.com/account gives 12 months; full history is at finzdata.com/shop. Then set FINZDATA_API_KEY. Nothing else changes.

Runs on open models with FinzData's free AI preview: no sign-up, no key. Answers are research, not investment advice.

FinzData Workspace on Cloudflare

  
A persistent workspace for your agent: it keeps files between sessions, runs code next to the data, and saves any strategy re-run into /workspace/strategies/ for analysis. Add it to any MCP client with a free FinzData key (email only, finzdata.com/account).
