What this server can do

8 functions, named and described by the server itself. Parameter names are shown because they say more about what a function does than its name usually does.

get_order_status(customer_address)
ウォレットアドレスの注文履歴を新しい順で返す。x402 で購入した注文は即時に order_status=3(決済完了)となり tx_hash を持つ。 Required: customer_address.
get_product(product_id)
1 つの商品の詳細を product_id で取得する。価格(JPYC 建て)・在庫・SKU・バリエーション・配送要否・対応チェーンを返す。購入の前に必ず呼んで、requires_shipping(配送先が必要か)と has_variants(オプション選択が必要か)を確認すること。 Required: product_id.
get_shop(shop_slug)
1 つのショップ(生産者・職人)の詳細を slug で取得する。ショップのストーリーや説明、対応ブロックチェーン、x402 決済が有効かどうかを返す。 Required: shop_slug.
list_products_in_shop(shop_slug)
1 つのショップの公開中の商品をすべて返す。価格(JPYC 建て)・在庫・バリエーション・配送要否・対応チェーンを含む。list_shops でショップを見つけたあと、その品揃えを見るのに使う。 Required: shop_slug.
list_shops
JPYC EC Platform に出店している公開ショップの一覧を返す。減農薬の農産物・地酒・伝統工芸品など、生産者から直接買えるショップが中心。各ショップの name / slug / 説明 / 対応チェーン / 商品点数を含む。商品を探す起点として最初に呼ぶとよい。
quote_checkout(items, is_gift, shop_id, shipping, customer_note, customer_email, gift_recipient, preferred_chain_id)
カートの内容で x402 チェックアウトの 1 回目を実行する。在庫を 5 分間仮押さえし、小計・割引・送料・合計(JPYC)と reservation_id、および署名対象の x402 PAYMENT-REQUIRED チャレンジ(base64url)を返す。エージェントはこのチャレンジを自分のウォレットで EIP-3009 TransferWithAuthorization 署名し、submit_payment に渡す。全 item は同一ショップである必要がある。配送が必要な商品があれば shipping を、贈答なら gift_recipient を必ず渡すこと。 Required: shop_id, items, customer_email.
search_products(tag, text, limit, category, max_price, min_price, shop_slug)
JPYC EC Platform 上の公開商品を横断検索する。減農薬米・地酒・伝統工芸品など、生産者から直接 JPYC で購入できる商品が対象。text は自然言語のキーワード(例: 『丹波 米』)で、商品名と説明に部分一致する。category / tag(産地・認証種別など)、価格帯(min_price / max_price、JPYC)、shop_slug で絞り込める。売上順で最大 50 件返す。
submit_payment(reservation_id, payment_signature)
quote_checkout で得た reservation_id と、エージェントが署名した x402 PaymentPayload(base64url)を渡して決済を確定する。サーバは facilitator 経由で on-chain settle し、確定した注文(order_number / tx_hash)を返す。署名は quote_checkout が返した payment_required の 内容に対する EIP-3009 TransferWithAuthorization であること。 Required: reservation_id, payment_signature.

Signals

These are separate measurements of different things. They are deliberately not combined into one score, because a popularity number that mixes website traffic with saves and stars cannot be checked or acted on.
