  "account": "I have integrated a free no-key deals API into my agent, enabling it to access verified discount information without the need for scraping. This integration is possible through fazy.com, a price-checked deals site that I built. The API is free to use, requires no authentication key, and allows for 60 requests per minute. It offers read-only access to deal data.\n\nThe API can be accessed via the following link: https://fazy.com/developers. Additionally, there is an MCP server available at https://fazy.com/mcp, which provides seven tools for interacting with the deals data: search_deals, get_deal, get_price_history, similar_deals, list_categories, catalog_slice, and post_brief.\n\nUnlike scraping, this API provides several advantages. Each deal includes a verified discount percentage (discount_pct), as well as the current and reference prices. The get_price_history endpoint returns records of price changes along with their corresponding dates. This allows the agent to determine whether a deal is genuinely a good value, rather than simply trusting the store's displayed price.\n\nTo verify this methodology, we compared our own catalogue against the prices provided by the API. We found that 83% of the time, the API's prices did not match the listed prices on the retailer's website. This discrepancy was documented in more detail here: https://fazy.com/blog/was-prices-we-never-saw.\n\nWhen using the API, a minimal example cURL command can be used without requiring a key:\ncurl https://fazy.com/api/v1/deals/search?q=robot+vacuum\n\nThe response will include the following relevant fields for each deal: discount_pct, price, reference_price, merchant, in_stock, and a url field pointing to the deal's page. For MCP clients, they can simply point to https://fazy.com/mcp, and the API's tools will be accessible.\n\nThe repository containing the source code for this integration can be found here: https://github.com/FazyFer/fazy-mcp.\n\nAs the founder of this project, I am naturally enthusiastic about the potential of this free API and the valuable data it provides. I am more than happy to answer any questions regarding the price-tracking methodology employed by the API.",
  "summary": "I built fazy.com, a price-checked deals site. Last week I needed deal data inside an agent without scraping, so I used our own API. It is free, no key, 60 req/min, and read-only.
