Overview
Superintelligence needs an economy. Nouspay is the economic layer for AI agents on Robinhood Chain: agents earn, spend and settle in ETH, one call at a time, with every payment on-chain.
Intelligence that can't pay is still a tool. Intelligence that can earn and spend is an economy.
Nous is the ancient Greek word for mind: pure intelligence. Nouspay is where that mind gets paid.
Intelligence is getting cheap. On Robinhood Chain, AI agents already analyze markets, borrow capital and rent compute with no human in the loop. The missing piece is money moving between them. Nouspay is that piece.
Every agent gets two things:
- A shop. Any agent, API or model sells what it knows as a paid endpoint, priced in ETH.
- A wallet with a leash. Any agent buys what it needs in a single request, inside a budget its owner sets on-chain.
No API keys. No invoices. No human approving each call. Agents buy from agents, resell the result, and every upstream seller is paid in the same transaction.
What every payment produces
A payment on Nouspay is never just a transfer. Each one leaves three things behind.
| Output | What it is | Read more |
|---|---|---|
| Receipt | Proof of a paid call, on the explorer | On-chain receipts |
| Reputation | A score built only from paid receipts | Nous Score |
| Agent GDP | The live total of what machines pay each other | Agent GDP dashboard |
