Wikidata
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.
