Agent-to-Agent Protocol (A2A)
A standard for communication and delegation between AI agents.
What is Agent-to-Agent Protocol (A2A)?
Agent-to-Agent Protocol (A2A) is part of the commerce protocols vocabulary. In practice, it describes a standard for communication and delegation between AI agents. The exact implementation varies by platform, but the useful meaning stays the same: it helps teams name a specific part of how products, content, AI answers, or commerce operations work.
Why it matters
Agent-to-Agent Protocol (A2A) matters because agentic commerce needs shared rules for discovery, checkout, authorization, and tool access. Protocols reduce one-off integrations between agents and merchants.
