Agent to Agent (A2A) protocol serves as an open standard for secure communication and collaboration among AI agents across different platforms.Introduced by Google in April 2025, A2A protocol is gaining attention for its seamless integration of various AI systems.It functions as a universal language for AI assistants, enabling knowledge sharing, task coordination, and improved user experience.A2A protocol fosters collaboration among diverse AI systems to enhance creativity and efficiency in developing advanced Gen AI solutions.It is set to revolutionize the AI development landscape by promoting interconnectedness and dynamism within the ecosystem.The A2A Protocol follows an HTTP-based communication model, facilitating interoperable services, consistent communication, and scalability.Each agent exposes an 'Agent Card' that details its identity, capabilities, endpoints, and authentication requirements for effective interaction.A2A leverages JSON-RPC for message exchange, ensuring simplicity in managing complex agent interactions.The protocol uses HTTP as its primary transport layer and includes SSE for real-time updates during task execution.A2A architecture comprises components like Agent Card, A2A Server, A2A Client, Task, Message, Part, Artifact, Streaming, and Push Notification.
