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**Swell.** Live /:models schema with field types and descriptions for every store. One full-access secret key per environment, with no scoped or read-only key.\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### Swell\n\n1. Call GET /:models once and cache it. It's the ground truth for custom fields\n2. Check `result.errors` after every write. A failed validation still returns 200\n3. Use `$set` to replace an array. A plain PUT merges arrays by element id and never shrinks them\n4. Use an sk_test_ key while testing. A bare sk_ prefix is live\n5. Keep `expand` and `include` small. Each level past the first three points adds rate-limit weight\n\n## Questions\n\n### Which is better for AI agents, Ecwid by Lightspeed or Swell?\n\nEcwid by Lightspeed scores 63.2 (B) on agent readiness against Swell's 55 (C), and leads in 4 of 7 scored categories.
