$PATH402 is a protocol that turns any URL path into a priced, tokenised market. Put a $ in front of a path segment and it becomes an economic object with a price curve, a supply count, holders who serve the content, and revenue that flows to participants.
The name combines:
Content behind $ path segments is $PATH402-gated. Each segment is an independent market.
$example.com → site-level token (cheap) $example.com/$blog → section token $example.com/$blog/$my-post → content token (the actual content)
Each $ segment creates a new market with its own price curve, supply, and token holders.
Price = Base / √(supply + 1). Early buyers pay more, price decreases with supply.
Key insight: Every buyer except the last achieves positive ROI.
Same price for everyone, regardless of supply.
Gentler price decrease than sqrt_decay.
Linear decrease to a minimum price.
The path402-mcp-server enables AI agents to interact with $PATH402 content.
npm install path402-mcp-server
{
"mcpServers": {
"path402": {
"command": "npx",
"args": ["path402-mcp-server"]
}
}
}Add this to your claude_desktop_config.json file.

The vision: an AI agent that starts with a small balance and grows it by:
This is possible because sqrt_decay pricing mathematically guarantees positive returns for early buyers. The agent's job is to identify good opportunities early.
