AnimeNewsNetwork vs Jikan

ANN's Encyclopedia API serves anime, manga, person, and company records as XML from cdn.animenewsnetwork.com/encyclopedia/api.xml, confirmed live with a real title lookup carrying Access-Control-Allow-Origin: *; the www.animenewsnetwork.com/encyclopedia/api.php page most integrations bookmark is actually the human-readable documentation front end rather than the data endpoint itself. It's free to use with attribution, capped at one request per second per IP.

Jikan is a free, keyless wrapper around MyAnimeList's public web data, confirmed live at api.jikan.moe/v4 with a real anime lookup and a wide-open Access-Control-Allow-Origin: * header. It has no official affiliation with MAL and can lag behind it after a MAL outage, but it remains the most widely used way to query MAL data without OAuth.
