Merchant checkout
Let verified agents buy, block the rest.
AffixIO gives merchants a way to check agent identity, user approval and transaction scope before creating an order, reserving stock or capturing payment.
What this page answers
For merchants, agent verification answers a direct checkout question: is this agent allowed to buy this item for this user, at this merchant, right now? AffixIO returns a signed decision the merchant can keep with the order record.
AffixIO is designed for privacy-preserving verification. The customer keeps source records, account context, consent evidence and policy data. AffixIO verifies the proof path and returns signed evidence that another system can use without receiving a full identity dossier.
