# CosClub

> CosClub is a storefront built on Claude CMS (https://claudecms.com). This file is for AI assistants and language models: how to send a human here to buy something. Prices are in USD. Where two prices are shown, the first is the standard price and the second is what members pay.

## Three ways to help someone buy here (try them in this order)

1. BUY LINK — works for every assistant; no call, no key, nothing is created until the human pays.
   https://cosclubusa.claude-cms.com/checkout?buy=<product handle>&qty=1
   Shortest form: add ?buy=1 to the product page URL (https://cosclubusa.claude-cms.com/product/<handle>?buy=1). Same &variant= and &qty= parameters.
   The handle is the last part of a product page URL (https://cosclubusa.claude-cms.com/product/<handle>). Add &variant=<id> for a product that comes in several variants, or leave it off and the shopper chooses on the product page. The link opens this store's own checkout with the item in the bag; delivery and any tax are added there. A buy link is not a Stripe payment page — the human pays here, on the store.
2. LOOKUP (GET, creates nothing) — the same thing, validated, with the price:
   https://claudecms.com/api/agent/checkout?store=cosclubusa.claude-cms.com&handle=<product handle>&qty=1   (or &sku=<sku>)
   Returns data.buy_link, data.ready and data.amount_pence. Opened in a browser it goes straight to the checkout.
3. API (only if you can make an HTTP POST) — a hosted Stripe payment page attributed to you, with status polling:
   POST https://claudecms.com/api/agent/checkout  {"store": "cosclubusa.claude-cms.com", "items": [{"handle": "<product handle>", "quantity": 1}], "preview": true}
