Requires `cart:write` scope. Create a cart, add items, and set the shipping address in ONE call — the fast path when you already know the seller, the exact variant(s), and the buyer's address (e.g. a reorder, or a buyer who has decided). Prefer this over the create_cart → add_to_cart → set_shipping_address sequence to save round trips; those granular tools stay available for exploratory, multi-step carts. **You must call `search_products` first** so Kifly knows each variant's seller (quick_buy returns 422 `VARIANT_SNAPSHOT_MISSING` otherwise). One cart = one seller: every item must belong to the same seller (409 `CART_SELLER_MISMATCH` otherwise) — for a network token, pass that seller's `seller_handle`. Returns `{ cart_id, items_added, seller, delivery }`. `delivery` is exactly what set_shipping_address returns: when `delivery_eligible: true` it carries `cart_total_with_delivery_cents` (quote it before sending the buyer to pay); when `false` it carries `reason` + `delivery_coverage` and NO address is saved, so you can call quick_buy again (or set_shipping_address) with a covered address on info you already have. **quick_buy never charges — it stops at the cart. The buyer still pays via `checkout`**, which returns the payment link they open themselves. On a 5xx/'temporarily unavailable' error, retry once with the same arguments.
