What is GTIN 5000112637922?

gtinfetch answers with the product, brand and maker the pages agree on, where it has been seen and when, and the pages themselves — one call, signed.

Is this barcode real?

gtinfetch checks the number is well-formed and whether any page on the web carries it. A valid check digit alone is not a product; a page is.

Who makes this product?

gtinfetch returns the maker and brand with the count of independent pages that agree, and marks the answer confirmed when two or more do.

Is this GTIN on sale in the UK?

gtinfetch returns where the GTIN has been seen — market and banner — with the last date, so an agent knows what it was true as of.

Is there an MCP server for barcode lookup?

gtinfetch.ai is one: a single tool, fetch_gtin, on the stock clients of AWS, Azure and Google, by GreenCore Solutions Corp. (GSC).

Is this a GTIN-13 or a case code?

gtinfetch stores every GTIN at fourteen digits and tells you the packaging level it was seen at, with the page.

A GTIN is a key, not a description. The thirteen digits say nothing about what the product is, who makes it, or where it is on a shelf. Every buying, listing, pricing and placement agent has to ask that question before it acts — and gtinfetch answers it, from pages it has read, with the pages attached.

Right answer or no answer. When gtinfetch hasn't seen a GTIN, it says unknown and goes looking. It never guesses.
