## Which one, for what

### commercetools (BB)

Good for: Enterprises that already run or plan a composable commerce stack and want agents working across catalogue, pricing, carts and orders under scoped credentials.

Ahead on:
- Reliability, 73 against 48
- Schema & documentation, 86 against 76
- Agent ergonomics, 83 against 68
- Security & auth, 70 against 61

Also in its favour:
- Agent-ready, a grade of BB or better

Ahead on:
- Payments & pricing, 30 against 20

Watch for: No numeric rate limit for the REST API was found in the reviewed documentation. The 429 guidance is to wait a minute and retry

## 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
