# Fizzl Buy

> The inkoper for AI agents: say what you need and Fizzl buys the right paid x402 API for you. It picks the service x402 Doctor has seen paying out day after day at a fair price, fills in its input, pays it (up to $0.01) and returns the answer, checked by TypeSafe Jev, with a signed receipt. $0.02 per purchase over x402 (USDC on Base or Solana); nothing is charged when no service delivers.

- POST https://buy.fizzl.eu/v1/buy with {"need": "weather forecast for Amsterdam tomorrow"} ($0.02)
