Agent Network Protocol
Overview
An open-source protocol enabling secure, decentralized communication among AI agents.
Best For Professions:
Agent Network Protocol (ANP) is an open-source communication protocol designed to facilitate secure, decentralized interactions among AI agents. It aims to become the 'HTTP of the Agentic Web Era' by providing a standardized framework that enables agents to connect, communicate, and collaborate efficiently. ANP's architecture comprises three layers: the Identity Layer for decentralized authentication using W3C DID standards, the Meta-Protocol Layer for dynamic protocol negotiation, and the Application Layer for semantic-based capability descriptions. This structure ensures interoperability, scalability, and secure communication across diverse AI systems.
Product overview
Capabilities, pricing and fit
Agent Network Protocol (ANP) is an open protocol stack for interoperable AI agents, not an agent application. Its specifications cover decentralized identity, human-readable names, agent descriptions and discovery, cross-domain messaging, and application-layer interactions such as payments.
Information as of August 9, 2026
What it can do
- Agent identity and naming
The stack defines did:wba identities and WNS handles for verifiable, human-readable agent identities across domains.[1]
- Description and discovery protocols
Agent descriptions publish capabilities and endpoints in machine-readable form so other agents can discover interoperable services.[1], [3]
- Messaging and application protocols
ANP 1.1 specifies direct and group messaging profiles, encryption, attachments, federation, and an application layer that includes payment interactions.[1]
Where it fits best
Pricing and availability
The public specifications are freely accessible; infrastructure and implementation costs depend on each deployment.[1], [3]
Platforms: Open web specifications, HTTP-based agent services[1], [2]
Access: Implemented by participating agent operators on existing web infrastructure[1], [2]
