A2AMessage

public final class GetExtendedAgentCardRequest
extends NonStreamingJSONRPCRequest<GetExtendedAgentCardParams>

JSON-RPC request to retrieve an agent's extended card with authenticated details.

This request fetches an extended version of the AgentCard that may contain additional information only available to authenticated clients, such as:

• Additional security scheme details
• Extended capability information
• Authenticated-only skills or interfaces
• Premium or restricted features

The agent must support authenticated extended cards (indicated by AgentCapabilities.extendedAgentCard() }) and the client must provide valid authentication credentials for this request to succeed.

This class implements the JSON-RPC GetExtendedAgentCard method as specified in the A2A Protocol.
