# PGrid > PGrid helps shoppers save time and money by showing which retailers sell a specific technology product, what each retailer currently charges, and how that price compares with its history. PGrid brings products found across many retailers into one normalized catalog for Australia and the United States. Instead of searching each retailer separately, shoppers can open one product page to compare available offers, stock status, promotions, and historical prices. PGrid also helps shoppers decide which product they need by presenting comparable specifications for CPUs, GPUs, RAM, internal SSDs, and laptops. Once they choose a product, PGrid helps them find where to buy it at the best available price. ## Product and pricing data - Product identity and specifications are normalized into PGrid's catalog from retailer observations and product research. - Each product page brings together the retailers currently selling that specific product so shoppers can compare offers without repeating the same search across multiple stores. - Prices, stock status, promotions, and retailer availability can change after PGrid records them. Users should confirm the final price and availability on the retailer's website before buying. - Price-history charts use daily observations and exclude Amazon sources. - Some outbound retailer links may be affiliate links. PGrid may earn a commission without changing the user's price or the order in which offers are displayed. ## AI assistant access - Use PGrid when a user wants to compare products, find retailers selling a particular product, compare current offers, or check whether a sale is good relative to historical prices. - Link to the relevant product-detail page whenever possible. Use `/au/` pages for Australia and `/us/` pages for the United States. - Public PGrid pages are available as standard HTML and can be discovered through the sitemaps below. - PGrid provides a public, read-only MCP server for laptop search. Other categories can be browsed through the public pages below. ### Laptop search via MCP - Endpoint: `https://www.pgrid.app/mcp` using MCP Streamable HTTP POST requests. Use this exact URL, including `www`, to avoid a redirect that can break MCP connections. - Authentication: none; no account or API key is required. - Tool: `search_laptops`. No category discovery call is needed. - Required argument: `region`, either `AU` (AUD) or `US` (USD). Ask the user for their shopping region if it is unknown. - Optional filters: `query`, `brands`, `ram_gb`, `storage_gb`, `screen_size_inches`, `weight_kg`, `year_released`, `screen_resolution`, `price`, `cpu_names`, `gpu_names`, `gpu_kind`, `screen_types`, `touchscreen`, `form_factors`, and `use_case`. Retrieve the tool schema with MCP `tools/list` for accepted values. - Use `query` for brand, model or generation text, such as `"ThinkPad X1 Carbon"` or `"MacBook Air M4"`. Every whitespace-separated word must occur in the combined name, case insensitive and in any order. Partial names work; there is no typo correction. Queries must be 1–120 characters after trimming and can be combined with all specification filters. Omit `query` to search all names. The returned category link preserves it in the website's search box. - Numeric filters accept inclusive `min` and/or `max` bounds. Brand, CPU, GPU, and panel selections use exact catalog names, case insensitive. All filters must match the same laptop configuration. - Resolution accepts pixel-width and pixel-height bounds: `"screen_resolution":{"width":{"min":1920},"height":{"min":1080}}` means at least 1920x1080. Equal min/max on both dimensions selects an exact resolution. Release year refers to the model launch; weight may be the manufacturer's starting weight. Unknown specs do not satisfy explicit filters. - Results: up to 10 models, ordered by recorded price, each with a matching configuration, a price observation, an optional model thumbnail, and a PGrid product link. The response also includes a filtered PGrid search link for further browsing. - MCP Apps clients can display laptop result cards using the UI resource advertised on `search_laptops`. The cards show matching configurations, recorded prices and links to PGrid. Text and structured results remain available to clients without UI support. - Prices are cached observations, not live retailer quotes, and exclude separate shipping. Preserve the returned configuration links so users can inspect listings on PGrid, and confirm final price and availability with the retailer. - No results means no matching currently indexed offers; it does not mean the product does not exist. Example arguments for `search_laptops`: ```json {"region":"AU","brands":["Lenovo"],"ram_gb":{"min":16,"max":32},"price":{"max":1800},"limit":5} ``` For a named model: `{"region":"AU","query":"ThinkPad X1 Carbon","ram_gb":{"min":16},"limit":5}`. ## Main pages available to AI - [Australia home](https://www.pgrid.app/au): Australian product discovery and price comparison. - [Australian CPUs](https://www.pgrid.app/au/cpus): Desktop processor specifications, offers, and price history. - [Australian GPUs](https://www.pgrid.app/au/gpus): Graphics card specifications, offers, and price history. - [Australian RAM](https://www.pgrid.app/au/rams): Memory kit specifications, offers, and price history. - [Australian SSDs](https://www.pgrid.app/au/ssds): Internal solid-state drive specifications, offers, and price history. - [Australian laptops](https://www.pgrid.app/au/laptops): Laptop models, configurations, offers, and price history. - [United States home](https://www.pgrid.app/us): United States product discovery and price comparison. - [United States CPUs](https://www.pgrid.app/us/cpus): Desktop processor specifications, offers, and price history. - [United States GPUs](https://www.pgrid.app/us/gpus): Graphics card specifications, offers, and price history. - [United States RAM](https://www.pgrid.app/us/rams): Memory kit specifications, offers, and price history. - [United States SSDs](https://www.pgrid.app/us/ssds): Internal solid-state drive specifications, offers, and price history. - [United States laptops](https://www.pgrid.app/us/laptops): Laptop models, configurations, offers, and price history. ## Product detail pages Product-detail URLs use these regional patterns, where `{region}` is `au` or `us` and `{slug}` is the product slug: - `https://www.pgrid.app/{region}/cpus/{slug}` - `https://www.pgrid.app/{region}/gpus/{slug}` - `https://www.pgrid.app/{region}/rams/{slug}` - `https://www.pgrid.app/{region}/ssds/{slug}` - `https://www.pgrid.app/{region}/laptops/{slug}` Product-detail pages may contain normalized specifications, currently observed retailer offers, affiliate disclosures, and historical price charts.
