Instead of visiting their website and copying every barcode, they simply ask their agent to run get_product_by_code on a list of UPCs. The tool returns the full metadata for all items in seconds. ### Verifying inventory accuracy An operations team member receives a pallet shipment and needs to confirm every item's brand and category before logging it into the system. They use get_product_by_code on a barcode, which immediately confirms both the manufacturer (via get_brand_details) and its proper classification. ### Researching book details A researcher needs to gather metadata for an old textbook. They use their agent to run lookups based on ISBNs, getting summary data and publisher information without needing a specialized library database connection. ## Benefits - Stop guessing about products. Use get_product_by_code to pull high-resolution details for any UPC or EAN barcode, including image links and descriptions. - Avoid manual cross-referencing by using get_brand_details. You can pinpoint the manufacturer behind a product just from its code. - Quickly understand your data structure by calling get_category_details. This helps you organize retail information into clear, actionable groups. - Expand beyond barcodes. Use search_products to query products when you only know the name or general SKU, giving broader coverage. - Validate your entire setup using check_api_status before running any major audit jobs, guaranteeing reliable data access. ## How It Works The bottom line is that you give a natural language request, and your agent handles the database calls automatically. 1. Your agent first calls check_api_status to confirm the Go-UPC connection is active. 2. Next, you ask your AI client to look up data using one of the specific tools, like get_product_by_code or search_products. 3. The tool returns structured JSON containing all the product details, brand names, and categories. ## Frequently Asked Questions **How do I start auditing product data using Go-UPC?** Start by asking your agent to check_api_status. This confirms the database is running before you run any lookups. Then, pass a UPC or EAN number to get_product_by_code for the full details. **Can Go-UPC help me find the manufacturer of a product?** Yes. After finding the product using get_product_by_code, you can use get_brand_details to pull specific information about the brand or manufacturer. **What if I only know the name, not the barcode? Should I use search_products?** Yes. If you don't have a UPC/EAN, use search_products with the product name. This is for general searching when specific codes aren't available. **Does Go-UPC provide category information? What tool should I use?** Yes, you can get this using get_category_details. It gives the organizational context and hierarchy for any product code you feed it. **What does using the `check_api_status` tool confirm about Go-UPC's service availability?** It confirms if the Go-UPC API is currently online and operational. Running this first lets you verify connectivity before attempting any complex product lookups. **What happens if I give an invalid barcode to `get_product_by_code`?** The tool returns a specific error message detailing the issue, such as an incorrect format or non-existent number. This helps you correct your data source immediately. **How do I track my usage when running `get_product_by_code`?** Your lookup history is logged in the platform dashboard. This feature lets you monitor your research volume and adhere to any set rate limits. **Can I use `get_product_by_code` for a list of barcodes, or does it only handle one at a time?** The tool processes UPC, EAN, or ISBN codes individually. You'll need to write a loop in your agent’s workflow to iterate through and process multiple codes. **How do I find my Go-UPC API Key?** Log in to your [**Go-UPC dashboard**](https://go-upc.com/dashboard), and you will find your API Key under the 'API' section. Copy and paste it below. **What barcode types are supported?** Go-UPC supports UPC-A, UPC-E, EAN-8, EAN-13, and ISBN-10/13 barcodes globally. **Can the agent show product images?** Yes. The `get_product_by_code` tool retrieves high-quality image URLs where available in the database, allowing your agent to provide visual context.
