Agent2Agent Protocol (A2A)
A2A is an open idea for agents from different vendors to discover each other and hand off tasks.
If it sticks, your “site” might be talked to by someone else’s agent. Machine-readable capabilities beat a cute homepage animation.
Still a protocol war. Ship useful APIs and docs either way.
Examples
- A research agent asks a booking agent to finish a reservation.
- A brand with only a PDF menu cannot participate.
