Keep the `session.id` it returns. 2. `POST /api/v1/cart` `action=add` with a **variant** id from the results. Prices live on variants, never on the product. 3. `POST /api/v1/cart` `action=billing`, then `action=shipping` with a `shipping_id`, then `action=payment` with a `token`. 4. `POST /api/v1/checkout` places the order. Idempotent per session. 5. When a human is available to tap, skip 2–4: `POST /api/v1/wallet` mints an Apple Pay / Google Pay link that collects their email, address and card. 6. Up to ten of those calls travel in one `POST /api/v1/batch`. ## Machine-readable data - [Product feed (JSON-LD)](https://apparel.monster/feeds/products.jsonl) — one schema.org `Product` per line - [Sitemap](https://apparel.monster/sitemap.xml) — every storefront URL - [llms.txt](https://apparel.monster/llms.txt) · [llms-full.txt](https://apparel.monster/llms-full.txt) - Any page: append `.md`, or send `Accept: text/markdown`, for a markdown twin - This document as JSON: [`/?mode=agent&format=json`](https://apparel.monster/?mode=agent&format=json)
