Details

From the project README

PennyRail

PennyRail is an autonomous machine-commerce yield engine: observe paid agent demand, identify monetizable capability gaps, publish the smallest reliable solution, charge per machine call, distribute it across agent-buying surfaces, and keep expanding the portfolio around proven demand.

Current build — v36 Revenue Broker

Current revenue loop:

PAID DEMAND → MAP/GAP → BUILD REUSABLE PRIMITIVE → PRICE → PUBLISH → SELL/BID → MEASURE → MULTIPLY

The production stack includes:

  • Base USDC x402 settlement with the proven Coinbase facilitator integration
  • 47 original factory capabilities plus proven-demand templates
  • dynamic revenue-product routes and machine-readable OpenAPI/x402 discovery
  • paid Agent402 Bestsellers intelligence every six hours (Demand Radar disabled while its upstream itemized feed is empty)
  • x402scan registration and x402 List review submission
  • the402 provider/catalog/request-bidding integration
  • optional OpenAI upstream broker capabilities, including live web search
  • private Radar dashboard with on-chain outside-revenue tracking, remembered admin access and one-click JSON copying

See README_REVENUE_BROKER_V36.md for the current revenue build. Historical version notes are intentionally preserved in the versioned README files.

Production secrets

Secrets belong in Vercel Production environment variables only. Never commit admin tokens, wallet credentials, provider API keys, webhook secrets or OpenAI keys to the repository.

Operating objective

Maximize aggregate machine-commerce gross profit across many tiny transactions. Current internal target: at least $1,000/day / $30,000/month, with no architecture ceiling. This is a target, not a guarantee.

From what the protocol is to installing your first server, these answers cover most first questions.

An open protocol that defines how AI applications connect to external tools and data in a uniform way. Clients talk to the model; MCP servers provide tools, resources and prompt templates. They exchange standard messages, so one server can be reused by many clients.
