## Verdicts

**Agentzon.** Public OpenAPI 3.1 description and llms.txt, with a whole-basket checkout that needs no account or key. The buyer pays on a private page, so a person completes each purchase. No status page, security.txt or registered seller address was found on agentzon.co, and 34 of 500 listed items cannot be bought.

**Vendure.** Full cart, coupon, shipping and payment flow in the GraphQL Shop API, with ErrorResult types an agent can branch on. No vendor-hosted API. Vendure Cloud is only partly available.

## Before you call either

### Agentzon

1. Search with GET /api/products. Use only items with checkoutAvailable true and a non-null unitAmount, because a null price means unavailable, never free
2. Send every item and quantity in one POST /api/checkout, with a new Idempotency-Key for each purchase attempt and the same key only to retry that basket
3. Show the buyer the product image from /api/products/{id}/image and get their approval before opening the checkout URL
4. Tell the buyer that catalogue prices exclude sales tax, that shipping is U.S. only and that change-of-mind returns exclude hygiene and food items
5. Keep the checkout URL and the orderToken private. A paid status confirms payment, not shipment

### Vendure

1. Keep the session token from the first Shop API response and send it on every call. It holds the active order
2. Check each mutation result's `__typename` and `errorCode`. Expected failures return 200 with an ErrorResult
3. Don't retry addItemToOrder blindly. Read the active order first, since a repeat adds the quantity again
4. For server-side work, enable `api-key` in authOptions.tokenMethod and give the key one role in one channel
5. Run 3.7.3 or later, and purge old job records, which may still hold session tokens
