02 WHY THIS EXISTS
THE MISSING LAYER
Rates are a record,
not a guess.
Every response carries its source, rate date, and fetch time. Historical endpoints let you answer what a price meant then — not what a cache thinks it means now.
01FETCHDaily snapshot pulled from the open source
02STOREDated reference row, never silently overwritten
03RETURNTraceable result with provenance attached
03 CAPABILITIES
One API. Four moves.
Look back
Ask what a rate meant on a specific date. Weekends and holidays resolve to the prior reference.
Date semanticsStay current
Daily snapshots expose source and fetch timestamps, so freshness is a fact — not a vibe.

Statistical forecasts ship as estimates with intervals and model metadata — never disguised as certainty.
