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.
Snipcart API + MCP
Hosted MCP server with 38 documented tools and a self-hostable Bun build. No server-side cart or checkout. Orders only come from the browser widget.
Before you call either
Agentzon
- Search with GET /api/products. Use only items with checkoutAvailable true and a non-null unitAmount, because a null price means unavailable, never free
- 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
- Show the buyer the product image from /api/products/{id}/image and get their approval before opening the checkout URL
- 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
- Keep the checkout URL and the orderToken private. A paid status confirms payment, not shipment
Snipcart API + MCP
- Use the agent for back-office jobs (orders, refunds, discounts, stock, abandoned carts), not for placing orders
- Start with a test-mode key (ST_ prefix) before switching to live (SL_)
- Send the key in X-Snipcart-Api-Key. OAuth-only clients can't connect
- Stay under 100 MCP requests a minute and 10 in flight per key
- Ignore unknown response fields. Snipcart adds fields without a new version
