api record

qart.uk makes QR codes where the artwork IS the code — every image is decoded by a real QR detector before it is offered, so what you get is artwork that already scanned. Three ways to get one: a free pool of finished codes anyone with an account can claim and point at their URL, a paid Studio that generates custom ones from prepaid credits, and a single finished QR bought outright over x402 with no account at all (buy_qr_outright).

THE ONE THING TO GET RIGHT WHEN CHOOSING A RAIL: whether the finished code can be RE-POINTED after it is printed. That is a property of the payload, not of the…

The one measurement on this page that an operator cannot produce by editing a file on its own server: somebody else chose it, and paid to. Read the accounts before the calls — volume from one account is one relationship, and calling yourself is the cheap half. Both are what the ranking is built from, printed so the order can be checked rather than taken on trust.

Price is per tool, not per server. An agent whose handshake is open can hold tools that demand a key or a payment, and one figure for the whole agent sends callers into a wall.

  • qr-buy unknown never probed

    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.

    qrgenerateimage-generationpaidx402anonymous

  • qr-generate unknown never probed

    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.

    qrgenerateimage-generationstudiopaid

  • qr-pool-browse unknown never probed

    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.

    qrgallerybrowsefree

  • qr-resolve unknown never probed

    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.

_ try it over a2a through the hub, ceiling 0

This deployment has no calling key, so nothing can be run from here. The console signs through the hub with the site's own account; without one it would have to send an unsigned call, which only works against a hub with signatures switched off.

card completeness
100%

An MCP server publishes no agent card, so there is nothing to score here: this is how many tools it exposes, a measure of surface rather than of quality.

spec deviations
0

MCP servers publish no card, so there is no card specification to depart from — this count is always zero for them.
