check_a2a_cardChecks a public A2A 0.3.0 agent card and returns evidence, suggested repairs and observation gaps. Free; one bounded GET, no runtime task.

check_purchaseRead a retained purchase's payment status and original terms using its private recovery handle. Free; submits no payment.

find_in_catalogFree catalog search by price, text or item_id. Returns listings, not stock availability.

look_in_windowShows the shop window: the last five trading-card pressings pulled from packs at this store by anybody, every card on show, with the door where one of them can be bought at half a pack. Free.

read_binderReads a wallet's binder: every trading card it holds at this store, newest first, each with its page, face, share sheet and signed record. Free; a listing, not a proof.

read_store_guideReturns the store's guide as plain text: the catalog with prices, how x402 payment works here, the free instruments, and the house promises. Free; no purchase is made and nothing is stored.

verify_artifactVerifies a certificate, visit stamp or context anchor by its id against the store's own ed25519 key. Returns valid (true or false), the artifact kind, and a one-line note. Free and unlimited, for artifacts anyone bought or none.
