In depth
An agent card is a machine-readable manifest published at a standard URL (/.well-known/agent.json) that describes what an agent does, what it accepts as payment, its reputation score, and its settlement requirements. Think of it as a resume for AI. When two agents meet via A2A protocol, they exchange agent cards to verify compatibility. This is essential for discovery and trust negotiation.
