The hubs are the records; A2A-Passport.ai issues the passport.

Context Cost
This is the approximate number of tokens consumed each time the server's tools are loaded into a model's context. Higher counts reduce the attention available for other tasks.

Tools (3)
🟢get_passport(subject, kind)
The signed passport of a product (a Global Trade Item Number, GTIN) or a retail banner (market/banner, e.g. FR/Carrefour): which hub holds its record, where it is on the record, its compliance records, who lists it, where the payment door is. Read live from the GSC hubs on every call; the first call issues version 1. subject = a GTIN (8 to 14 digits) or market/banner; kind = gtin or banner (optional).
