## 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 63
- Schema & documentation, 86 against 68
- Agent ergonomics, 83 against 65
- Security & auth, 70 against 35
- Transparency & trust, 81 against 50

Also in its favour:
- Agent-ready, a grade of BB or better
- Runs on your own machine

Watch for: No public price. The pricing page describes order-based pricing and sends buyers to sales

### Swell (C)

Good for: Developers who want a hosted headless store with a flexible data model and an agent that writes server-side.

Ahead on:
- Payments & pricing, 25 against 20

Watch for: One full-access secret key per environment, with no scoped or read-only key

## 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.

**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.

## 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

### Swell

1. Call GET /:models once and cache it. It's the ground truth for custom fields
2. Check `result.errors` after every write. A failed validation still returns 200
3. Use `$set` to replace an array. A plain PUT merges arrays by element id and never shrinks them
4. Use an sk_test_ key while testing. A bare sk_ prefix is live
5. Keep `expand` and `include` small. Each level past the first three points adds rate-limit weight
