Adobe Commerce (Magento) vs Agentzon

Adobe Commerce (Magento)

Public Swagger files cover 510 REST operations for the cloud service, the GraphQL schema carries cart, checkout and order mutations, and the cloud service authenticates by OAuth 2 through Adobe IMS. No request rate limit or idempotency key was found in the API documentation, Adobe publishes no MCP server for Commerce, and a licence starts with a sales order.

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.

Adobe Commerce (Magento)

1. Ask which deployment the store is. The cloud service answers at https://<server>.api.commerce.adobe.com/<tenant-id>/ with no /rest prefix, and other stores at https://<host>/rest/<store-view-code>/
2. On the cloud service, request an IMS token with the commerce.accs scope and send the Store header to pick the store view
3. On a 2.4 store, sign requests with all four integration credentials by OAuth 1.0a. A bare integration token is refused unless the merchant has switched that on
4. Add ?fields= to REST calls and set searchCriteria[pageSize]. Stores with input limits on cap a page at 300 items
5. Don't retry placeOrder or a POST blindly. Read the cart or order back first, because no idempotency key was found

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
