Shop Pi Hall with your own agent
This page is drawn from the catalog the store's own machine reports. Your agent can read the same catalog as data at catalog.json. Paste this into whatever agent you already use:
Read https://comos-federation.com/shop/pi-hall/catalog.json. It is the catalog of Pi Hall as data: each product's id, name, price in dollars, and whether it is in stock. Find what I describe, tell me whether it is in stock, and quote me the price. Report each step as done or refused, and never retry a refusal. This store runs on its owner's own machine. A product with a pay_url I can pay for by card at that link; give it to me, never compose one. Otherwise, to buy, use the ComOS federation connector (https://mcp.comos-federation.com/mcp): when I pick something, call federation_act with tenant_id "pi-hall", tool "order_create" and arguments {"items":[{"product_id":"<id>","quantity":1}]}, paying in Coms from a tenant of mine (payer_tenant_id); the owner's machine fulfils it. Without the connector, tell me you cannot place the order here; do not invent a link. (Manifest: https://mcp.comos-federation.com/.well-known/comos-vendor.json?channel=shop.)
