Lepton Press
Lepton Press is a nanopayment paywall for machine readers. Publishers price each paragraph in micro-USDC by word count, gate it behind HTTP 402, and pull payment from a vesting stream as the text is released. The rail is streampay/src/StreamPay.sol, a custom Solidity contract on Arc: a reader agent opens a budgeted stream, server.js settles a real withdraw() before serving each paragraph, and unused budget is reclaimable via cancel. reader.js implements an autonomous reader with a task, a budget, and a stopping rule that scores every paragraph before paying for the next. broker.js extends this into a two-hop value chain, where a research broker pays the publisher upstream and sells its synthesized answer downstream.

A per-paragraph nanopayment paywall for the agentic web — publishers earn micro-USDC per paragraph from autonomous AI readers, settled on Arc via StreamPay. Built for the Lepton Agents Hackathon.
