1. Protocol Abstract
   The x402 Mesh Protocol specifies an open standard for autonomous AI agents to discover, authenticate, traverse, and financially settle compute and knowledge exchanges without human intervention. It introduces CiteMesh (the two-sided citation economy), Attention Options (risk-free attention futures), Claim Anchors (anti-hallucination provenance gates), and Embedded Micro-Royalties (EIP-2981 compatible perpetual downstream creator tolls).

2. Core Architectural Pillars
   2.1. Federated Node Discovery & Recursive Traversal
   Every participant in the x402 Mesh exposes a canonical root manifest and advertises recommended next-hop routes via HTTP headers:

GET /.well-known/x402
GET /x402/mesh
X-x402-Next: /v1/geomesh/options/chain
2.2. Embedded Sovereignty & Micro-Royalties (EIP-2981)
Every byte of intelligence returned by an SML node embeds an unalterable downstream royalty claim. When downstream agents repackage and monetize SML intelligence, a 2.5% toll is automatically remitted on-chain.

X-X402-Royalty-Recipient: 0x4e14B249D9A4c9c9352D780eCEB508A8eB7a7700
X-X402-Royalty-Bps: 250
X-X402-License: SML-Attributed-Commercial-v1
2.3. CiteMesh: Two-Sided Citation Marketplace
AI engines (Perplexity, ChatGPT, Claude) query POST /v1/match for citable sources. When a source is cited, POST /v1/cite/attest automatically triggers a sub-cent x402 micropayment to the content creator while SML retains a 10% facilitation toll.

Endpoint Role Pricing
POST /v1/sources/register Creator registers domain for CiteScore evaluation (0-100) Free
POST /v1/match Agent queries for ranked, high-authority citable sources $0.001 USDC
POST /v1/cite/attest Cryptographically stamps citation & triggers creator payout $0.005 USDC
GET /v1/market/intent-stream Live firehose of real-time AI agent search demand $5,000 / mo
2.4. Citation Options Exchange (Attention Derivatives)
Brands buy Call/Put options on topic clusters, paying a $50–$120 non-refundable option premium upfront to lock in citation prices. If unexercised, 100% of the premium is pure profit for the exchange.

1. W3C Decentralized Identity (did:sml) Agents authenticate using their cryptographic keypair mapped to did:sml:0x{wallet}, which exposes their 402Proof credit rating, capabilities, and automated payment authorizations.

1. Client Tool Integrations LangChain & CrewAI Tool Definition Integrate CiteMesh citation attribution into any LangChain agent in 3 lines of code:

from langchain.tools import Tool
import requests

def cite_geomesh(source_url: str, agent_wallet: str) -> dict:
res = requests.post("https://apis.scriptmasterlabs.com/v1/cite/attest", json={
"source_url": source_url,
"agent_wallet": agent_wallet
})
return res.json()
