MangaDex
MangaDex's API was reconfirmed live at api.mangadex.org with a real manga listing, but a direct cross-origin GET and an OPTIONS preflight both came back without an Access-Control-Allow-Origin header, so browser-based CORS calls fail — corrected to no. Authentication was also corrected from a bare API key to MangaDex's real scheme: OAuth 2 personal clients using a password grant tied to a user's account, since MangaDex has no API-key concept — public reads need no auth at all. The API and its manga remain entirely free, funded by the site rather than gated behind the API.
AuthenticationOAuthRequires an OAuth flow; expect app registration.
HTTPSSupportedTraffic is encrypted in transit.
