Browse the API catalog

Every API AnyAPI can serve right now, with its normalized input and output contract's location, its USD pricing, and the sources behind it. Reading the catalog is free and needs no key. Each entry's method and path are the gateway's own authority on how to call it: use them rather than rebuilding a route from the slug. Schemas are omitted here to keep the response small; GET /v1/apis/{sku} returns them for one API.
