Path402 — Tokenised Web Content for AI Agents

Official registry AI and agents

AI agents discover, acquire, and re-serve tokenised web content via the $402 protocol

Install

Add this to your client's MCP configuration (Claude Desktop: claude_desktop_config.json; Cursor: .cursor/mcp.json; VS Code and others use the same "mcpServers" shape).

NPM package path402
Claude Code
claude mcp add path402-tokenised-web-content-for-ai-age -e 'PATH402_API_URL=<PATH402_API_URL>' -e 'PATH402_DEFAULT_BUDGET=<PATH402_DEFAULT_BUDGET>' -e 'PATH402_WALLET_WIF=<your path402_wallet_wif>' -- npx -y path402@1.3.2

            }
        }
    }
}

path402

Turn AI agents into autonomous economic actors. Run a $402 network node.

This package includes:

  • MCP Server — AI agent tools for Claude, GPT, etc.
  • path402d Daemon — Index tokens, serve content, earn rewards


Quick Start

Installation
npm install -g path402
Run path402d Daemon
path402d start

This starts a $402 network node that:

  • INDEX — Reads BSV blockchain, tracks all $402 tokens
  • VALIDATE — Confirms token ownership before serving
  • SERVE — Delivers content to verified token holders
  • EARN — Receives $402 rewards via PoW20
path402d CLI Commands
path402d start           # Start the daemon
path402d status          # Check if running
path402d stop            # Stop the daemon
path402d config          # Show configuration
path402d mine            # Start PoW20 mining (experimental)
path402d --help          # Full help
Why Run path402d?

PoW forces operators into the open. Big nodes can't hide.

The purpose of PoW20 is NOT just to reward work—it's to force operators into visibility:

  • Computational cost → Capital investment → Scale
  • Scale → Physical presence → Regulatory visibility
  • Big nodes must identify themselves

No anonymous propaganda dealers running underground BitTorrent clients with no accountability.

Add to your claude_desktop_config.json:

{
  "mcpServers": {
    "path402": {
      "command": "npx",
      "args": ["path402"],
      "env": {
        "PATH402_API_URL": "https://path402.com",

First Conversation
You: "Discover what's available at $example.com"

Claude: [Uses path402_discover to probe the $address]
        Found 3 nested tokens:
        - $example.com/$blog (500 sats, 0 supply)
        - $example.com/$api (1000 sats, 0 supply)
        - $example.com/$premium (2500 sats, 0 supply)

You: "Evaluate if $example.com/$blog is worth acquiring"

Claude: [Uses path402_evaluate and path402_economics]
        ROI Analysis:
        - Current price: 500 sats
        - Breakeven: 1 serve at current rates
        - Projected ROI: 340% over 30 days
        Recommendation: ACQUIRE (high confidence)

You: "Acquire 10 tokens"

Claude: [Uses path402_acquire]
        Acquired 10 $example.com/$blog tokens
        Total cost: 5,000 sats
        New balance: 10 tokens

The $402 Protocol

What is $402?

$402 turns URL paths into tokenized markets. Any path prefixed with $ becomes an economic object:

$example.com              → Site-level token
$example.com/$api         → API access token
$example.com/$api/$premium → Premium tier token

Each token has:

  • Price curve (ascending bonding curve by default)
  • Supply counter (increases with each acquisition)
  • Holder registry (who owns what)
  • Revenue distribution (issuer/facilitator split)
Ascending Bonding Curve

Price is determined by remaining treasury, not speculation:

price = base_price / √(treasury_remaining + 1)
TreasuryPrice% Sold
500M10 sats0%
100M22 sats80%
10M71 sats98%
1M224 sats99.8%
1K7,072 sats99.9998%

Key insight: Early buyers always get better prices. This creates natural incentives for discovery and early adoption.

Self-Funding Agents

Agents can become economically self-sustaining:

  1. Acquire tokens at current price
  2. Serve content to other agents/users
  3. Earn revenue from serving
  4. Reinvest profits into more tokens

The ascending bonding curve mathematically guarantees that early acquirers can achieve positive ROI through serving.

Use Cases

1. Content Discovery Agent

Agent explores the $402 namespace, discovering valuable content:

1. path402_batch_discover(["$news.com", "$research.org", "$data.io"])
2. path402_evaluate() on promising finds
3. path402_acquire() undervalued tokens
4. path402_serve() to users who request content
2. API Gateway Agent

Agent manages API access for a team:

1. path402_acquire("$api.service.com", 1000)
2. path402_wallet() to track usage
3. path402_serve() when team members need API calls
4. path402_acquire() more when balance runs low
3. Research Agent

Agent gathers information from paywalled sources:

1. path402_discover() research databases
2. path402_economics() to evaluate cost/benefit
3. path402_acquire() access to valuable sources
4. Compile research using acquired content
4. Revenue-Generating Agent

Agent that pays for itself:

1. path402_acquire() tokens at low prices
2. path402_servable() to list inventory
3. path402_serve() to other agents
4. path402_wallet() to track profits
5. Reinvest profits into more tokens
