Nobel Prize vs Wikidata

The official Nobel Prize API serves structured, keyless JSON on every laureate, prize category, and award year back to 1901, including prize amounts (nominal and inflation-adjusted) and links between related records. A live query against api.nobelprize.org/2.1/nobelPrizes needs no key and returns a wildcard Access-Control-Allow-Origin header, so it's directly callable from browser code.

Wikidata's action API exposes the structured, multilingual knowledge base behind Wikipedia's infoboxes — entity search, full item/property retrieval, and SPARQL-style queries over billions of statements. All read operations (wbsearchentities, wbgetentities, wbgetclaims, and friends) are keyless; OAuth only comes into play for authenticated edits/writes, which this directory entry isn't about. CORS is opt-in per request via the documented `origin=*` query parameter, which returns a wildcard Access-Control-Allow-Origin.
