Look up a product barcode number: identify and validate EAN-13, EAN-8, UPC-A, UPC-E, GTIN-14, ISBN-13/10, ISSN and ISMN codes (wrong check digits are reported with the correct digit), convert between forms (GTIN-14, EAN-13, UPC-A, ISBN-10 <-> 13) and decode the GS1 prefix. Then fetch product data from open databases: name, brand, quantity, categories, image, labels, Nutri-Score (food, cosmetics, pet food via Open Food Facts) or title, authors, publisher and cover (books via Open Library).

Using Roundhouse, tell me whether this x402 merchant is worth paying: how many distinct
agents have paid it, how recently, and for what.

The /v0 API needs an API key (`authorization: Bearer rh_live_…`) on everything except
/v0/unified* and /v0/endpoints. Either pay over x402 (mint a personal key for $0.01 at
GET https://api.roundhouseai.io/v0/test/x402), or ask me for an organization key, which I create at
https://roundhouseai.io/dashboard/connections. If you have neither, ask before going further.

If you do not have Roundhouse tools or skills installed, read
https://roundhouseai.io/skill.md first — it is the whole procedure.
