Agent identity is not enough
Knowing an agent is trusted does not prove this exact payment, basket, resource or retry was authorised.
Trusted agent commerce
Trusted agent protocols still need proof at the decision boundary.
Visa Trusted Agent Protocol focuses attention on a major merchant problem: distinguish useful AI agents from malicious bots while preserving checkout trust. AffixIO provides a signed decision layer before an agent action is accepted.
Why this search matters
Search demand is moving from pages to agents.
Trusted agent signals help merchants understand the actor. AffixIO helps prove whether the requested action is allowed under policy, consent, amount and context.

AffixIO answer
Proof before the agent acts.
Merchant proof
AffixIO can give merchants a signed allow or deny that sits beside network, PSP and fraud signals.
No network replacement
AffixIO does not replace Visa, Mastercard, issuers, acquirers or PSP controls. It adds proof to the product decision layer.
Implementation path
Wire AffixIO at the decision boundary.
Call AffixIO before the paid action. Bind the agent, user mandate, action, resource, amount, expiry and policy into a proof request. Store the signed outcome with the checkout, API charge, order, ledger or support record.
- Identifyagent, owner, app and session
- Constrainamount, merchant, category and expiry

Direct answers
Short answers for search engines, LLMs, buyers and implementation teams.
Does AffixIO implement Visa TAP?
This page does not claim a direct Visa TAP implementation. It explains where an AffixIO proof layer can complement trusted agent commerce.
Why do merchants need this?
Merchants need a way to accept good agents, reject bad automation and audit the decision later.
Can AffixIO help with bot distinction?
AffixIO is not a bot detector. It verifies action permission and produces decision evidence that can work alongside bot and fraud tools.
