What you get back

Every response is one envelope: { data, meta, provenance }. data is the value, meta carries a live confidence score and a stalenessfigure, and provenance names the contributing venues and the method — so you can audit freshness and lineage without a second call.

Live today. Pulling data needs a free API key; browsing this page and the catalog needs none.
