ColourLovers vs Rijksmuseum
ColourLovers runs a free, keyless REST API behind its color-palette community site, covering colors, palettes, patterns, and user profiles. A live request against /api/palettes returned real palette data over both HTTP and HTTPS, in JSON or XML, with no Access-Control-Allow-Origin header in the response. Results carry the site's Attribution-NonCommercial-ShareAlike license, so reuse needs credit and stays non-commercial.
The Rijksmuseum has replaced its old key-gated REST collection API with a free, fully keyless Linked Open Data service: a Linked Art-based Search API at data.rijksmuseum.nl/search/collection and a Persistent Identifier Resolver at id.rijksmuseum.nl, both returning JSON-LD. A live GET against the real search endpoint returned 1,463 genuine matching results for a Rembrandt query with Access-Control-Allow-Origin: *, and its own docs explicitly state no API key is needed — correcting the stored url off its retired /object-metadata/api/ path (now a 404), auth API Key -> None, and cors unknown -> yes.
