Your AI agents can't talk to each other. We wrote the dictionary.

As you build multi-agent AI systems, a critical question emerges: how will they communicate securely and effectively? Without a standard protocol, your ecosystem becomes a collection of isolated silos.

This whitepaper provides a definitive comparison of the three leading agent communication protocols—Google's A2A, IBM's ACP, and our own AgentTalk. Understand the fundamental trade-offs between capability discovery, uniform messaging, and verifiable, secure transactions. Make the right architectural choice for a scalable and interoperable future.
