Agent2Agent (A2A)
Agent2Agent (A2A) is a protocol enabling direct communication and task delegation between AI agents without exposing sensitive user data.
In commerce, A2A allows a buyer's personal agent to coordinate with a merchant's agent — negotiating, confirming, and delegating across a transaction. The Universal Commerce Protocol supports A2A as one of its integration options for agent-to-agent commerce journeys.
A2A points to where agentic commerce is heading: not a buyer's agent operating a merchant's website, but two agents transacting directly with each other. For brands, that means a future in which the merchant-side agent is itself a commercial asset that must be built and maintained.
