Any series in the Federal Reserve's FRED database (800k+ US & international economic time series). HOW TO USE: if you know the series id, pass seriesId to get the series metadata (title, units, frequency, seasonal adjustment, observation range, last updated) + its most-recent observations (date + value, newest first; optionally bound the range with start/end YYYY-MM-DD and cap with limit). If you DON'T know the id, pass query to full-text search the catalog (returns ids + titles + units + frequency, most-popular first) — then call again with the seriesId you found. Popular ids: UNRATE (unemployment rate), CPIAUCSL (CPI), PCEPI (PCE price index), GDP / GDPC1 (nominal / real GDP), PAYEMS (nonfarm payrolls), FEDFUNDS (fed funds rate), DGS10 / DGS2 (10yr / 2yr Treasury), T10Y2Y (10y-2y spread), MORTGAGE30US (30yr mortgage), SP500, VIXCLS (VIX), DEXUSEU (USD/EUR), DCOILWTICO (WTI oil), HOUST (housing starts), UMCSENT (consumer sentiment), M2SL (M2 money supply). Each series' units and frequency come back in the metadata so you know how to read the values. Free, public-domain for most series (FRED attribution). Distinct from econ.indicator (a small curated headline set) — this is the FULL catalog. Companion endpoints: econ.fred-releases (when reports are published — the data calendar) and econ.fred-vintage (point-in-time / revised values for honest backtesting).
