Decentralized identity, discovery, messaging, and payment protocols for interoperable AI agents.
Protocol stack
ANP is organized as a layered protocol suite so implementations can adopt the foundation first, then add messaging, discovery, and payment capabilities as needed.
DID:WBA defines verifiable agent identities, while WNS adds human-readable handles for sharing and resolving agents.
06Negotiation patterns allow agents to exchange protocol capabilities and choose interoperable interaction paths.
07 / 08Agents describe services, capabilities, endpoints, and discovery mechanisms in a way other agents can consume.
09 / P1-P8Direct messaging, group messaging, E2EE, attachments, and federation are split into focused profiles.
10AP2 brings payment authorization, receipts, signatures, and DID-based key distribution into ANP.
Architecture
The protocol separates identity, negotiation, semantics, security overlays, and application flows, keeping each layer easier to implement and evolve.
