StatCite

StatCite returns official economic statistics — World Bank WDI, IMF WEO/Fiscal Monitor (current vintage via the IMF's own DataMapper API), and ECB reference rates — where every number ships with a full citation: source, dataset, series ID, canonical URL, license, retrieval date, and a ready-to-paste citation sentence.

Its verify_stat tool checks any claimed economic figure against the official series and returns a verdict (match / close / mismatch / cannot_verify) with diagnostics for the classic errors: wrong year, percent-vs-decimal slips, and millions/billions scale confusion. verify_claims batch-checks up to 15 claims from a draft in one call.

An as_of parameter enables revision-aware verification: check whether a claim was true against the IMF WEO/Fiscal Monitor edition that was current on a given historical date, not just today's revised figure.

42 curated indicators across 200+ economies, inflation adjustment, and historical FX conversion (including ~90 currencies the ECB set doesn't cover). Free, read-only, no authentication required.
