Tokens never expire, there is no test mode or idempotency key, API access needs a paid plan, and carts are built only in the browser.\n\n**Square.** The REST API has a public OpenAPI 3.0 spec, OAuth scopes split by read and write for each resource, idempotency keys on writes and a free sandbox. 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## Before you call either\n\n### Ecwid by Lightspeed\n\n1. Send the token as `Authorization: Bearer` to `https://app.ecwid.com/api/v3/{storeId}`. Tokens in the query string stopped working in March 2025\n2. Use the secret token server-side only. The public token reads enabled products and places orders that are not marked paid\n3. Add `responseFields`, for example `total,items(id,name,price)`, to keep responses small, and page with `offset` and `limit` (maximum 100)\n4. Stay under 600 requests a minute per token and wait the `Retry-After` seconds on a 429. Repeated calls with a bad token get the token and IP blocked for longer\n5. Work in a separate test store. There is no test mode, and `POST /orders` writes a real order with no idempotency key\n6. After changing an app's scopes, uninstall and reinstall it, then replace the stored tokens. The old ones stop working\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## Questions\n\n### Which is better for AI agents, Ecwid by Lightspeed or Square?\n\nSquare scores 69.2 (B) on agent readiness against Ecwid by Lightspeed's 63.2 (B), and leads in 5 of 7 scored categories.
