It cannot place or follow orders, and the Checkout API needs separate approval. The documentation renders only in a browser, and the API terms date from 2020 and still name a previous affiliate network.\n\n**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.\n\n## Before you call either\n\n### Walmart Affiliate Marketing API\n\n1. Generate a fresh WM_SEC.AUTH_SIGNATURE for each call, because a signature older than 180 seconds is rejected\n2. Keep below 5,000 calls a day per application\n3. Pass the Impact publisher ID so returned links earn commission\n4. Hand purchases to the person through the returned product link, since the affiliate API cannot check out\n\n### Zillow in Claude\n\n1. Use the server at https://mcp.zillow.com/api/v2 from Anthropic's directory, not the third-party Zillow servers in the MCP registry\n2. Search on objective criteria (location, price, size, amenities, schools, commute), since the release says the connector won't search on protected characteristics\n3. Treat Zestimates and affordability results as estimates, and hand tours, agent contact and financing to the person through Zillow's links\n4. Read tools/list before planning, because no tool reference is published and the input fields aren't documented anywhere we could read\n\n## Questions\n\n### Which is better for AI agents, Walmart Affiliate Marketing API or Zillow in Claude?\n\nWalmart Affiliate Marketing API scores 38.6 (E) on agent readiness against Zillow in Claude's 28.6 (F), and leads in 5 of 7 scored categories.
