FAQ

Are containers and collections both included?

Yes — both. Containers (cases/capsules) and collections (map drop pools) share the same DTO.

Are prices live?

Yes — each item in a collection is joined with its current Steam price.

How do I list every collection?

GET /steam/api/cs/collections. For a single one by slug, GET /steam/api/cs/collection/{slug}.
