Endpoint
scvd.store/api/buy/window_pick
Task: Take one pressing off the last five anybody pulled here, chosen by the day seed, for half a pack. Returns: One pressing from the shop window (the last five pulled from packs, free at /api/paywall/window), chosen by the day seed and moved to your binder re-signed, with its print number, page and verify URL. Instant; refused before payment while the window is empty or inside your twelve-hour lock. Price: $0.49 USDC (x402 v2; network from the current quote). Latency: delivered in the purchase response, same request. Verify: GET /api/verify/{id} — free, unlimited, forever (live sample: cert_4dww28dx5j). Constraints: The window is the last five pressings pulled from packs store-wide; an empty window, or a second pick inside twelve hours, refuses before payment terms and nothing is charged; Which card you get is HMAC-SHA256 over the day seed, your wallet, your certificate and the window's card ids; recomputable once the seed is revealed. It may be somebody else's Condition; No price on a card, no store-run market, nothing bought back. a window pick, One card from the shop window, the last five pressings pulled from packs here by anybody, free to look at at /api/paywall/window. Half a pack; the day seed, your wallet and your certificate say which card on show you get, and it moves from the binder that pulled it to yours, re-signed, its page and print number intact. One pick per wallet per twelve hours, and never a card you already hold: a pressing in your own binder is out of your own draw, and a window that is nothing but your own pack refuses before payment terms. A card entitles the holder to a card.
Score
The score is built from observations we collect ourselves: how the endpoint responds, what the envelope contains, how stable the price and the recipient are, who pays and how often. It is deterministic — the same input always produces the same result.
We do not publish the exact methodology yet. If you own this endpoint, write to us and we will show you, item by item, what drags the score down.

Is this your endpoint?
The score is built only from public observations. If something we recorded is wrong — say our prober hit you during maintenance — write to us. We will recheck and publish your reply next to the score.
We do not delete accurate observations. The prober makes at most one request per second per host and only asks for the payment challenge — it never pays and never takes content.
