Verdicts

commercetools

A public OpenAPI file with 822 operations, per-resource OAuth scopes and a managed MCP server whose tools an administrator selects per agent. Prices are quoted by sales only, and the HTTP API publishes no platform-wide rate limit. A 60-day trial needs no card.

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

commercetools

  1. Use the auth and API hosts for the project's region, such as auth.europe-west1.gcp.commercetools.com and api.europe-west1.gcp.commercetools.com. There are five regions
  2. Send the resource's current version with every update or delete. On 409 ConcurrentModification, re-read the resource and retry only if the change is still needed
  3. Retry 502 and 503 with exponential backoff from 200 ms, honour Retry-After, and check Content-Type before parsing an error body
  4. For MCP, ask for an API Client scoped to mcp:{projectKey}:{mcpServerKey} and a server limited to the tools the task needs, not all
  5. Keep page size at or under 500 and offset at or under 10,000. Product Search returns at most 100 per request

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
