Catalog API
Catalog API
Browse and resolve the LynCut asset catalog — stickers, music, fonts, effects, filters, transitions, and text presets served from CDN.
The catalog exposes every published creative asset in LynCut — the same library the editor's panels read from. All catalog endpoints are public: no API key required, responses are CDN-cacheable, and media resolves to signed R2 URLs.
Public endpoints
Catalog reads need no authentication. Rate limits still apply per IP — cache responses client-side where possible.
