What is Laso Finance?
Laso Finance is a payment API that lets AI agents spend cryptocurrency. Using the x402 protocol, 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.Get started
