The MCP server is in beta and its remote instance reaches production only. No numeric REST rate limits or SLA were found, and the status page recorded widespread errors on 27 September 2026.\n\n**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.\n\n## Before you call either\n\n### Square\n\n1. Test against the sandbox first with the local MCP server and `SANDBOX=true`. The remote server at mcp.squareup.com reaches production only\n2. Set `DISALLOW_WRITES=true` on the local MCP server when the task only reads\n3. Call `get_service_info`, then `get_type_info`, before each `make_api_request`. The request body is otherwise untyped\n4. Send a fresh `idempotency_key` on every write, and reuse it when retrying the same write\n5. Pin `Square-Version` in each request. Use a page cursor within 5 minutes of receiving it\n\n### Wix Stores and eCommerce API\n\n1. Send the API key in `Authorization` with `wix-site-id` for site calls or `wix-account-id` for account calls, never both\n2. Fetch the product first and pass `product.revision` on every Catalogue V3 update, or the call fails with 409\n3. Use Cart V2 for new work. The older eCommerce Cart and Checkout APIs were deprecated on 5 August 2026\n4. Request `cursorPaging.limit` of at most 100 on Query Products and use Search Products for lookups by name\n5. Over MCP, read the method page with `ReadFullDocsArticle` before `CallWixSiteAPI`. Responses are cut at 50,000 characters by default\n\n## Questions\n\n### Which is better for AI agents, Square or Wix Stores and eCommerce API?\n\nSquare scores 69.2 (B) on agent readiness against Wix Stores and eCommerce API's 61.4 (C), and leads in 5 of 7 scored categories.
