Get one RESO Property by ListingKey

Returns one entitlement-scoped Property entity addressed by its stable RESO ListingKey. OData string-key syntax uses single quotes; a quote inside the key is escaped by doubling it. $select and the Realty $ignorenulls option can reduce the response. An out-of-scope or unknown key returns the same 404 not_found response.

Authorization
