Ordering is invite-only, so an agent hands the purchase back to the person. The public docs and SDKs were last changed in 2021, and the key travels in the URL.\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### Best Buy Developer API\n\n1. Add format=json to Products, Stores and Categories calls. XML is the default for those three\n2. Use show= with only the fields you need and pageSize up to 100, and switch to cursorMark=* beyond ten pages\n3. Batch SKU lookups with the in operator to stay under 5 calls a second. A 403 can mean the limit, not a bad key\n4. Send the person to the product URL to buy. The Commerce API that places orders needs a partner invitation\n5. Cache responses for no more than 72 hours and refresh prices before quoting them, as the terms require\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, Best Buy Developer API or Zillow in Claude?\n\nBest Buy Developer API scores 39.1 (E) on agent readiness against Zillow in Claude's 28.6 (F), and leads in 4 of 7 scored categories.
