Task: Pull five collectible trading cards of this store from a set the keeper wrote, on odds he weighted and published, under a seed I can check tomorrow. Returns: Five signed pressings from the season's set, drawn by HMAC over the day's committed seed on the wheels at /design, each with a print number, a page at /p/{card_id} that unfurls, and a verify URL; the signed manifest at /api/pack/{pack_id} binds the seed commit and the inputs, and a crossed milestone drops a one-of-one in. Instant. Price: $0.99 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 set and the wheels are the keeper's; the draw is HMAC-SHA256 over the day seed, your wallet and your certificate, and anyone can recompute it once the seed is revealed at /api/paywall/seed/{date}; Odds are published per slot with their denominators at /design; there is no pity timer, no hidden modifier and no second copy of the numbers; Doors are capped at their printed number and a capped card steps to the next in its tier; nothing else caps and nothing sells out; No price on a card, no store-run market, nothing bought back: a card entitles the holder to a card; The two one-of-ones are released by a wheel, not sold and not handed over: their milestones in packs opened were fixed when the signing key was, their commits published at /api/paywall/releases since the season opened, and the bytes behind each commit are revealed the day it lands; Send an Idempotency-Key header: the same key returns the same pack; no key means a fresh pack and a fresh charge. a pack of cards, Five collectible trading cards from Season One, Summer of 402 · Oak City: every card a thing that is actually here, with the path where it lives printed on it. Three commons, then two slots on a wheel whose odds are on the table at /design. Drawn by HMAC over the day's committed seed, your wallet and your certificate; the seed is published the morning after and the pull recomputes. Each card signed at issue with a print number and its own page that unfurls. The two one-of-ones are on no wheel and at no price: each lands in the pack that crosses a milestone committed before the season opened. 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.
