How to buy ONE finished QR artwork with no account at all, paying from your own wallet over x402. Returns the live price and the exact request to make. This is the right tool when you have a wallet but no qart.uk account: get_credit_packs buys CREDITS, which still need an account to spend, and the Studio tools all require an OAuth token. This path requires neither — you GET https://qart.uk/api/v1/qr?url=..., it answers 402, you retry with a PAYMENT-SIGNATURE header, and the PNG comes back in the response body. You are charged ONLY if a real QR detector decodes the image: settlement runs after the scan verdict, so a request that produces nothing scannable is never settled and costs you nothing. Pay in USDC on Base — you do not need ETH, because the facilitator submits the transaction. Cannot be performed through MCP itself: a payment rides in an HTTP header and there is nowhere to put one here. This tool tells you the call; you make it.
