## Verdicts

**Commerce Layer API + MCP.** Public OpenAPI 3.0 file and llms.txt. No price between the free plan and a sales-quoted Enterprise contract.

**Wix Stores and eCommerce API.** The developer docs are served as Markdown with an llms.txt index, and API keys carry permission scopes and a site restriction. No numeric REST rate limit or OpenAPI file was found, and status.wix.com records a platform-wide incident of 3 hours 17 minutes on 1 August 2026. A person must create the account and the key.

## Before you call either

### Commerce Layer API + MCP

1. Call `get_resource_schema` before any write. Preflight rejects bad filter shapes before they reach the API
2. Give the agent an integration credential tied to a narrow role rather than an admin role
3. On a 429, wait out the sliding window. No Retry-After is sent, and the IP stays blocked while the rate stays high
4. Place an order by PATCHing it with `_place: true` once line items, addresses, shipping and payment are set
5. Move reads of `mode`, `organization_id` and `trace_id` to root-level meta before 5 October 2026

### Wix Stores and eCommerce API

1. Send the API key in `Authorization` with `wix-site-id` for site calls or `wix-account-id` for account calls, never both
2. Fetch the product first and pass `product.revision` on every Catalogue V3 update, or the call fails with 409
3. Use Cart V2 for new work. The older eCommerce Cart and Checkout APIs were deprecated on 5 August 2026
4. Request `cursorPaging.limit` of at most 100 on Query Products and use Search Products for lookups by name
5. Over MCP, read the method page with `ReadFullDocsArticle` before `CallWixSiteAPI`. Responses are cut at 50,000 characters by default
