What is nuez?
nuez is the payment layer for AI agents. It provides a prepaid wallet with its own CVU, a REST API, and an MCP server — so any agent can transfer funds, check balances, and manage transactions with the same guarantees as a human, but without the friction.
The problem
Section titled “The problem”AI agents can reason. They can’t pay.
Connecting an agent to payment rails today means one of two extremes:
- Give the agent full bank credentials → unacceptable risk (a hallucination or prompt injection can drain the account)
- Require human approval for every operation → kills autonomy, defeats the purpose
There’s no middle ground. No “trust me up to this amount, ask me above it.” That missing policy engine between the agent and the payment rail is the gap nuez fills.
What nuez provides
Section titled “What nuez provides”| Layer | What it does |
|---|---|
| Wallet / CVU | Prepaid account with its own CVU. Fund it from any bank, Mercado Pago, or Ualá. |
| REST API | https://api.nuez.app/v1 — standard HTTP endpoints for transfers, balances, and transaction history. |
| MCP server | https://mcp.nuez.app — exposes nuez as MCP tools so any agent using Claude, Cursor, or a custom framework can call it natively. |
| Policy engine | Rules per API key: spending threshold, scopes, and allowlists. Operations under the threshold execute automatically. Above it, the owner gets a WhatsApp notification and approves with a tap. |
Who is it for?
Section titled “Who is it for?”- Developers building AI agents that need to move money in Argentina
- AI agents (Claude, GPT, custom) that need a payment tool they can call directly
- Agencies and freelancers automating payments on behalf of clients
Current status
Section titled “Current status”nuez is in private beta. The wallet, transfer, and MCP tools are functional in sandbox. Production rails require signing up for the waitlist at nuez.app.
