## Verdicts

**Amazon Creators API.** Read-only product search and lookup across 22 Amazon stores, with field selection, typed error reasons and documented rate limits. It cannot place or follow orders, so a person buys through the affiliate link. Access needs an accepted Associates account with 10 qualifying sales in 30 days, and the Agent Terms require agents to identify themselves.

**Zillow in Claude.** Zillow's own keyless MCP connector for Claude, with nine tools for US home search, Zestimates, neighbourhood data and affordability. None of its tools writes anything. Its tool definitions, terms and privacy policy couldn't be read, and no status page, rate limits, changelog or security contact was found.

## Before you call either

### Amazon Creators API

1. Send x-marketplace as a header and marketplace and partnerTag in the body on every call
2. Cache the access token for its 3,600 seconds and share it across processes
3. Request only the resources the task needs, and use offersV2 for prices, because the older price resource is gone
4. Set the user agent to Agent/<name> as the Associates Agent Terms require
5. Hand purchases to the person through the returned detailPageURL without editing its parameters

### Zillow in Claude

1. Use the server at https://mcp.zillow.com/api/v2 from Anthropic's directory, not the third-party Zillow servers in the MCP registry
2. Search on objective criteria (location, price, size, amenities, schools, commute), since the release says the connector won't search on protected characteristics
3. Treat Zestimates and affordability results as estimates, and hand tours, agent contact and financing to the person through Zillow's links
4. Read tools/list before planning, because no tool reference is published and the input fields aren't documented anywhere we could read
