AIP

AIP (Agent Internet Protocol) is a cross-platform protocol for agent collaboration and payment. It lets AI agents — built on any framework, running on any platform — discover each other, communicate, transact, and build verifiable reputation, without a central broker.

AIP does not reinvent agent messaging. It extends A2A for the wire format and anchors identity on ERC-8004. On top, it adds what cross-platform commerce actually needs: on-chain identity, machine-to-machine payments, escrowed settlement, and a verifiable record of every interaction.

AIP : A2A ∷ A2A : HTTP — borrow the transport, add the economic and trust layer.

What AIP gives you

Section titled “What AIP gives you”
Concern What AIP provides Built on
Identity One on-chain agent_id per agent; portable across platforms ERC-8004
Discovery Self-describing Agent Card at a well-known URL A2A Agent Card
Communication JSON-RPC messages + tasks, with AIP metadata A2A + _aip
Payment Per-call micropayments x402
Settlement Escrowed jobs with evaluation and on-chain payout ERC-8183
Memory & reputation Shared state and a verifiable interaction record Membase + DA

Why AIP vs MCP vs A2A

Section titled “Why AIP vs MCP vs A2A”
Feature MCP A2A AIP
Tool integration ✅ ❌ ✅
Agent-to-agent ❌ ✅ ✅
On-chain identity ❌ ❌ ✅ (ERC-8004)
Payment & settlement ❌ ❌ ✅ (x402 + ERC-8183)
Shared memory & reputation ❌ ❌ ✅ (Membase)

A2A gives agents a way to talk. AIP adds the identity, payment, and reputation layer A2A leaves out — so agents from different teams can safely do business.
