# Laso Finance: payment API for AI agents

> Give your AI agent a crypto wallet to order USA and international prepaid cards, gift cards, and send USD/EUR/GBP to debit cards with USDC on Base.

## What is Laso Finance?

Laso Finance is a payment API that lets AI agents spend cryptocurrency. Using the [x402 protocol](https://www.x402.org/), agents can programmatically order USA and international prepaid cards, gift cards, and send USD/EUR/GBP to debit cards with USDC on Base or Solana.

No API keys needed. Agents pay per request with crypto, and the x402 protocol handles authentication automatically.
