# List Vendors

`GET /catalog/vendors`

List the valid vendor identifiers + display names + host mapping.

Price-enrichment keys off the INTERNAL vendor enum (TWENTYONEAT, CGSTL,
VANTOR, SIIS, SPACEWILL, IMPROSAT, ESA) — a business name like "21AT" silently
prices at $0. This endpoint makes the right identifier discoverable so callers
don't have to guess: each entry carries the `vendor` enum (what pricing
expects), the catalog `host` (what the search endpoints use on the wire), a
human `displayName`, and the `constellation`.
