- Browse the Free QR Pool
List the pre-generated, scan-verified QR artwork currently claimable for free, one per style, with a preview image URL for each. Works without credentials; claiming one requires a signed-in account.
- Buy a QR Artwork Outright
How to buy one scan-verified QR artwork outright, paying from your own wallet over x402 — no account, no bearer token, no credits. Asking here returns the live price and the exact call to make; the purchase itself is an HTTP request to https://qart.uk/api/v1/qr, because a payment needs a PAYMENT-SIGNATURE header and this JSON-RPC transport has nowhere to put one. That endpoint answers 402, and on the paid retry the PNG comes back in the response. You are charged ONLY if a real QR detector decodes the image: settlement follows the scan verdict, so a request that produces nothing scannable costs nothing.
- Generate Custom QR Artwork
Generate scan-verified QR artwork for a destination URL and a described style. Returns a Task: images arrive as artifacts one at a time over several minutes, each carrying its own scan verdict, and the task can be cancelled at any point. SPENDS REAL MONEY — requires an OAuth bearer token with the qart:studio scope, and consumes the account's prepaid credits.
- Resolve a qart.uk Code
Given a scanned qart.uk code or its alias, report where it currently points, or that it has been retired. Does not count as a scan and does not affect the owner's statistics. Works without credentials.
