⚪x402_buy(need)
Paid ($0.02 via x402 in USDC on Base, Solana, Algorand or Stellar, or RLUSD on the XRP Ledger, inside the call): say what your agent needs ("weather forecast for Amsterdam tomorrow", "BTC price", "EUR to USD rate") and Fizzl buys the right paid x402 API, the one x402 Doctor has seen paying out day after day at a fair price (up to $0.01), fills in its input, pays it from its own wallet and returns the answer, checked by TypeSafe Jev, with which service it came from and a signed receipt. Nothing is charged when no seller delivers. To see first what it would buy, call x402_pick (free).
