Use price and availability together

The lowest visible price is only one signal; stock status and merchant fit matter before purchase.

Keep the crawl path intentional

This route has its own canonical URL, metadata, H1, and structured data for category-level search intent.

Check live prices yourself

Pull the same best guardian prices your browser just saw

Every product card on this page is a snapshot of BuyWhere's live catalog. If you are building an agent, a price tracker, or just want to verify a listing, you can hit the same endpoint the page renders. No scraping, no proxies — one signed HTTP call and the JSON comes back. Three ways in:

  1. 1. REST — direct catalog search

    No auth required for low-volume reads. Returns the same merchant metadata this page ranks on.

    curl "https://api.buywhere.ai/v1/products/search?q=best%20guardian&country_code=us&limit=6"
  2. 2. MCP — tool-callable from any agent

    Connect once and your agent can call search_products, find_best_price, and get_deals directly.

  3. 3. Self-serve API key — one call, no dashboard

    Higher rate limits and MCP access need a key. Register takes one POST; the free tier is enough for most prototypes.

    curl -X POST "https://api.buywhere.ai/v1/auth/register?verify=false" \
      -H "Content-Type: application/json" \
      -d '{"agent_name":"my-agent"}'
