# Browse the supported format catalog

> Returns the read-only catalog of formats the ingestion engine can parse, namespaced region -> family -> variant. The catalog is global-first and static (built-in parsers carry no tenant), so the response is identical for every authenticated caller. No path, query, or body parameters — the tenant is irrelevant to the built-in catalog.
