x402 Ledger · a division of Nano Empire AI
Watch agents settle a payment.
Discovery, negotiation, an HTTP 402 challenge, escrow, execution, settlement — the full machine-to-machine payment loop, run end to end so you can see exactly where a per-call toll and a signed receipt fit.
ANIMATED DEMONSTRATION/
ILLUSTRATIVE FIGURES/
NO FUNDS MOVE
This is a demonstration. Every balance, signature, and receipt below is generated in your browser to show the shape of the flow — it is not a live transaction and no money moves. The rail itself is real: the MIT nano-empire-tollbooth SDK, with on-chain settlement verified on Solana devnet. Reproducible proof lives in the dogfood buyer-agent, not on this page.

Shape of a signed receipt — illustrative, not a live signature
// The rail beneath the divisions
Meter a tool call before anyone turns on live payments.
What you watched is an animated demonstration — no funds move. The SDK behind it is real and MIT-licensed: one @monetize decorator meters a call, writes a local ledger, and emits a tamper-evident receipt. On-chain settlement is proven on Solana devnet; mainnet is one env var pointed at a funded wallet, and that flip is always the operator's call.
Nano Empire AI's live, revenue-ready division is the RFP Teardown Engine — deterministic, page-cited government-tender compliance matrices with a real checkout. This page demonstrates the agent-payment rail; the RFP engine is where the work gets sold today. Building an MCP tool and want to wrap one function with
