Get an Estate Agent

Retrieves the full record of a single existing estate agent relation.

A developer calls this endpoint to look up an estate agent already registered in Bloxs, typically before displaying its details, updating its information, or linking related records such as real estate objects. An estate agent represents a real estate brokerage or agency relation, and does not carry a relation type, supplier type, or gender-based salutation, since these concepts are specific to Persons, Organisations, and Suppliers respectively.
