CalcFi Open Data: 34 Free CC-BY Financial and Macro Time Series Mirrored from Primary Sources

Free, CC-BY-4.0 financial and macro datasets — a daily-refreshed mirror of CalcFi (https://calcfi.app) with full primary-source provenance. 34 time series across 11 categories: mortgage rates (Freddie Mac PMMS, Treasury yields), interest rates (Federal Funds, Prime), inflation (CPI, PCE), employment (BLS unemployment, labor participation, hourly earnings), energy (WTI, Brent, gasoline), foreign exchange (USD/EUR, USD/GBP, JPY/USD), cryptocurrency (BTC, ETH, SOL), FDIC deposit and CD rates, credit card and personal loan rates, copper and corn benchmarks, and World Bank global indicators.

Each series is a complete Frictionless Data Package with data.csv (history with provenance headers), datapackage.json (schema descriptor), and README.md (per-series source citation, live URL, quickstart code). Data is mirrored verbatim from primary sources (FRED, BLS, BEA, US Treasury, Freddie Mac, FDIC, EIA, Federal Reserve H.10, World Bank, CoinGecko, IMF). No smoothing, imputation, or seasonal adjustment beyond what the primary source publishes. Refreshed daily at 05:00 UTC.
