PSP supports agent payment tokens

Checks whether the payment provider we detected on your shop documents a way to accept payments that an AI agent initiates with a token held for the shopper.

What we check

We take the payment providers fingerprinted on your shop and look each one up in a table we verified against the providers' own documentation on 2026-09-18. The question is seller-side: can a merchant on this provider accept an agent-held payment token, such as Stripe Shared Payment Tokens, ACP delegated payment, or a UCP payment handler? Today the table records Stripe, Adyen, PayPal and Braintree as documenting this; Mollie and Klarna as not documenting it (Klarna appears in agentic commerce on the buyer side, which is a different question); and Checkout.com, PayU and Przelewy24 as undetermined, because their own developer documentation settles nothing either way.

Why it matters

An agent that has found, compared and filled a basket still has to pay. If your provider has no path for an agent-held payment instrument, the agent reaches your payment step and cannot present anything your checkout accepts, so the purchase ends there.

How we check

No extra request is made; this reads the payment providers detected during the scan. PASS when at least one detected provider documents agent-initiated payments. FAIL only when every detected provider is recorded, with medium or high confidence, as having no agent-token path. We SKIP when no payment provider was detected, and when any detected provider is missing from the table or marked low confidence and none is documented as supporting it: a provider we have not researched is not evidence that it lacks support.

How to fix it

  1. Add a provider with a documented agent-token path alongside your current one. Stripe Shared Payment Tokens, Adyen agentic payments and PayPal/Braintree Agent Ready all publish seller-side guides.
  2. Ask your current provider for a written answer on agent-initiated payments (ACP delegated payment, UCP payment handlers), and keep the answer with its date.
  3. On Shopify, WooCommerce or a custom build, the answer depends on the payment gateway you connect, not on the platform itself; check the gateway's own agentic-commerce documentation.
  4. Until then, expect agent traffic to reach your payment step and stop there.

What good looks like

This check reads no markup of yours; it reads which payment provider your checkout loads.
A shop passes when that provider documents agent-held payment tokens, for example:

<!-- your checkout loads a provider that documents them -->
<script src="https://js.stripe.com/v3/"></script>

Provider documentation we rely on (verified 2026-09-18):
  Stripe    Shared Payment Tokens
  Adyen     agentic commerce (ACP / UCP)
  PayPal    Agent Ready (through Braintree)
