triggerfetch

Is your product in the answer when a shopper asks? For one barcode in one country: found (whether ChatGPT, Claude, Gemini and Grok name it, and where in the four it sits), likely why (the most probable reason from what the record shows: wrong name, missing barcode, not in the catalogue the AI reads, not verified, not orderable) and corrected (the brand's own words bound to its barcode, with a new receipt). One free check a day; then the brand's agent signs in.

Sign in the brand's agent with its claim_seat identity: give the card address the brand claimed its seat with and one of its barcodes. Returns a token to place at https://<card domain>/.well-known/triggerfetch.txt or in DNS TXT _triggerfetch.<domain>; then call sign_in_verify.

Finish sign-in: the token is read at the brand's domain and the barcode's seat on the hub must be the seat of that card. Returns the session key for check_product and correct_product.

Corrected: the signed-in brand gives the words it wants its product found by (name, brand, size) for one barcode and one country. Writes a new match record on matchfetch and issues a new receipt on rco.wefetch.ai that supersedes the last one for that barcode. The next index edition shows whether the answer changed.

The current edition of The AI Grocery Shopping Index: what the AIs answer when shoppers ask, by category and country, with each product by barcode, its answer share and shelf position, and orderable coverage per country.
