AGENT-TO-AGENT PROTOCOL
A2A defines the interoperability contract. Band provides the production fabric.
Band is the collaboration layer for your agent ecosystem. It does not replace your framework, protocol, or observability stack. It connects and governs all of them so your agents can work together.
A2A and ACP define how agents should talk. Band makes that conversation reliable, observable, and governable at scale.
