# Get dataset coverage and account access

`GET /v1/commodities/{code}/coverage`

Returns the versioned, customer-safe coverage contract for one catalog
code. History bounds come from an asynchronously refreshed materialized
snapshot; this request does not scan the raw price table. Availability
and account entitlement are separate so callers can distinguish missing
data from plan access.
