# Agent card

> In A2A, a published description of an agent's identity, skills, endpoint and authentication requirements.

In the Agent2Agent protocol, an agent card is a JSON metadata document published by an A2A server that describes the agent's identity, capabilities, skills, service endpoint and authentication requirements. Other agents read the card to decide whether and how to interact with it. A card is a self-description, so for financial use it should be backed by verifiable signals about the operator rather than trusted on its own.
