A person engaged for the purpose of bringing his or her principal and a third party into a contractual relationship is called an "agent." An agent is a person who represents another person, known as the principal, in dealings with third parties. The agent has the authority to act on behalf of the principal and make agreements with third parties, such as buying or selling goods or services. The agent is typically paid a commission for their services. In this sense, an agent acts as a mediator between the principal and the third party, facilitating the formation of a contract.
