Callook.info vs Nobel Prize
Callook.info is a free, keyless lookup service for FCC-licensed US amateur radio callsigns, returning license status, operator class, name, and registered address as either JSON or XML. A live request for a real callsign returns a wildcard Access-Control-Allow-Origin header with no authentication required, confirming it's safe to call directly from browser code.
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.
