## Verdicts

**Ecwid by Lightspeed.** The REST API has 40 access scopes, a published limit of 600 requests a minute per token with `Retry-After` on a 429, field selection through `responseFields`, and Markdown docs with an llms.txt index. 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.

**Elastic Path API + MCP.** Cart, promotion code, checkout and order endpoints cover the whole test flow. MCP server exposes 95 tools with full CRUD, no read-only mode and no public source or licence.

## Before you call either

### Ecwid by Lightspeed

1. Send the token as `Authorization: Bearer` to `https://app.ecwid.com/api/v3/{storeId}`. Tokens in the query string stopped working in March 2025
2. Use the secret token server-side only. The public token reads enabled products and places orders that are not marked paid
3. Add `responseFields`, for example `total,items(id,name,price)`, to keep responses small, and page with `offset` and `limit` (maximum 100)
4. 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
5. Work in a separate test store. There is no test mode, and `POST /orders` writes a real order with no idempotency key
6. After changing an app's scopes, uninstall and reinstall it, then replace the stored tokens. The old ones stop working

### Elastic Path API + MCP

1. Use a client_credentials token server-side only. It has full CRUD on the store
2. Pick the base URL for the store's region (useast or euwest), or every call returns 401
3. Loading the MCP server costs 95 tool definitions, so enable it only for agents that need the back office
4. On a 429, wait a few seconds and retry. No Retry-After header is sent
5. Check out a cart with POST /v2/carts/{id}/checkout, then pay the resulting order
