## Which one, for what

### Spree Commerce (BB)

Good for: Teams that want to own a Rails commerce backend with marketplace, B2B and multi-region functions and drive it through REST.

Ahead on:
- Reliability, 82 against 48
- Schema & documentation, 85 against 76
- Agent ergonomics, 90 against 68
- Payments & pricing, 55 against 30

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

Watch for: Six GitHub security advisories between 8 January and 20 July 2026, four rated High, most of them access-control flaws on guest carts, orders and addresses

### Wix Stores and eCommerce API (C)

Good for: An agent managing a merchant's existing Wix store or building a headless storefront on Wix.

Ahead on:
- Transparency & trust, 77 against 60

Also in its favour:
- A hosted endpoint, with nothing to install
- No incidents deducted, where Spree Commerce loses 5 points for them

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

**Spree Commerce.** A self-hosted BSD 3-Clause platform with public OpenAPI files for the Store and Admin APIs, scoped secret keys, documented rate limits and idempotency keys on cart and checkout calls. GitHub lists six security advisories between January and July 2026, four rated High, and the default docs describe the 6.0 release candidate while 5.6.1 is the stable release.

**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

### Spree Commerce

1. Send a publishable key in `X-Spree-Api-Key` on every Store API call. Add `X-Spree-Token` with the cart token for guest carts, or a customer JWT as a Bearer token
2. Send `Idempotency-Key` with the cart token or a customer JWT on cart, payment and completion calls. A request carrying only the publishable key is never cached
3. Ask for `fields` and `expand` explicitly. Relations are left out by default and `limit` stops at 100
4. Use a secret key with the narrowest scopes for the Admin API. `read_all` gives a read-only key, and the CLI's auto-minted local key is read-only
5. Read the docs under `/docs/v5` for a 5.6 store. The default docs describe 6.0, which renames shipments to fulfilments and splits carts from orders

### 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
