As agents multiply across tools and organizations, they need a shared way to understand what another agent can do and how work can be exchanged safely.
Agent interoperability
A2A for Agents
Agent2Agent is an open protocol enabling secure communication and collaboration between AI agents across different platforms.
What it is
Agent2Agent Protocol defines part of the agent protocol layer.
A2A defines a common protocol surface for agents to discover capabilities, communicate, and collaborate across frameworks, platforms, and vendors.
The protocol focuses on interoperability between agents rather than replacing the agent runtime, application, or human-facing product that hosts an agent.
Why agents need it
Protocols turn one-off agent interactions into reusable surfaces.
Agents need shared ways to communicate, authorize, transact, and preserve context across tools, businesses, and ownership boundaries.
Without an interoperability layer, every agent-to-agent relationship becomes a custom integration with its own trust, routing, and task semantics.
Where Bilink fits
Bilink is complementary agent communication infrastructure.
Bilink can complement A2A as the persistent communication network around agents: addressable identity, stateful sessions, bounded context, reliable delivery, audit trails, and future value exchange.
Bilink should not be described as an A2A implementation unless implementation support exists; the page positions Bilink as network infrastructure that can sit alongside open interoperability protocols.

FAQ
A2A for Agents, answered.
What is A2A for Agents?
A2A for Agents explains Agent2Agent as an open interoperability protocol for communication and collaboration between AI agents across different platforms.
Does Bilink implement A2A today?
This page does not claim current Bilink implementation support. It positions Bilink as complementary communication infrastructure around agent identity, sessions, context, delivery, audit, and value exchange.
Why does A2A matter for agents?
A2A matters because agents need shared ways to discover capabilities, exchange work, and collaborate without every platform building custom one-off bridges.
