Buy a USA prepaid Visa card loaded with EXACTLY the requested balance ($5–$1000). Dynamic x402 price = amount + fee (3% min 0.50 USDC) — the 402 instructions carry the exact total. Returns 202 with an operation_id: poll card_status until ready (~10s), then fetch the number with card_get. US merchants only; non-reloadable (spend across transactions until depleted); max 6 cards per agent per rolling 24h (issuer limit).
