}🟢buy_ticket(ticket_id, first_name, last_name, email, tx_hash, ...)
Buy the ticket for a flight from search_flights, paid in USDC. Call it first without payment to get the price, wallet address and MPP challenges. After sending the USDC, call it again with tx_hash and chain (or an MPP credential in _meta "org.paymentauth/credential"). x402 clients can instead sign one of the offers in error.data.x402 and retry with the PaymentPayload in _meta "x402/payment", with no gas needed. Returns the ticket link and PDF.
