The catalog is a public, key-free endpoint so your code can discover models at runtime:
GET https://flopco.in/v1/modelsFilter with ?type=text|image|video|audio and ?tag=vision|edit|pixel|.... Choose the response encoding with ?format=json (default), xml, or php (a PHP serialize() string). Each model reports id, capabilities, acceptsInitImage, cost (FLOP), license, and a status of live or preview.
