--- title: "Merchant decision guide for agent checkout | Agent Ready Checkout" description: "Pick platform, processor, size band and agent channels, and get the protocols that apply, the integration path, dated cost lines and open risks." canonical: https://agentreadycheckout.com/guide site: "Agent Ready Checkout" last_updated: 2026-11-04 section: "Decision guide" --- # Merchant decision guide for agent checkout | Agent Ready Checkout > Pick platform, processor, size band and agent channels, and get the protocols that apply, the integration path, dated cost lines and open risks. Source: https://agentreadycheckout.com/guide Site: Agent Ready Checkout Last reviewed: 2026-11-04 # Merchant decision guide In short The decision guide answers one question: given your platform, processor, size band and the channels where customers shop with agents, which protocols apply and what does the integration cost and risk? It holds 18 answers, six platforms by three size bands, each from published pricing and documentation dated 4 Nov 2026. Without JavaScript every answer is on this page. ## Pick your stack All 18 answers are shown below. With JavaScript the form narrows them to your platform, size band, processor and channels. Without JavaScript the form filters by platform and size band only; processor and channel choices are ignored, so read the processor table and the channel lists below. **Check it:** after you choose a path, scan your own domain to see how an agent reads it today. The pay-layer check we recommend is [Ora](https://ora.ai/?utm_source=agentreadycheckout.com&utm_medium=referral&utm_campaign=guide), whose Payments layer runs 6 checks across x402, MPP, UCP, ACP and AP2 (GET /api/checks, read 5 Nov 2026). Its score is Ora's reading, not ours, and Ora is not part of the matrix. [The six checks against the matrix](https://agentreadycheckout.com/method/ora-payments-layer), [the other scanners that test payments](https://agentreadycheckout.com/method/pay-layer-checkers). ## What your processor adds The decision form's processor choice reads from this table. A status here is the processor's own cell in the matrix for each protocol the guide recommends. | Processor | UCP | ACP | Link for agents | Visa IC | Mastercard Agent Pay | Visa TAP | AP2 | | --- | --- | --- | --- | --- | --- | --- | --- | | Stripe | live | live | live | announced | announced | announced | no statement found | | Adyen | pilot | pilot | no statement found | announced | announced | announced | announced | | PayPal | live | live | no statement found | no statement found | announced | no statement found | announced | | Checkout.com | pilot | pilot | no statement found | pilot | pilot | pilot | pilot | | Braintree | live | live | no statement found | no statement found | announced | no statement found | no statement found | | Coinbase | no statement found | no statement found | no statement found | no statement found | no statement found | announced | announced | | Crossmint | live | no statement found | no statement found | live | live | no statement found | announced | | Skyfire | no statement found | no statement found | no statement found | announced | announced | no statement found | no statement found | | PayOS | no statement found | no statement found | no statement found | no statement found | announced | no statement found | no statement found | | Worldpay | announced | announced | no statement found | no statement found | no statement found | announced | announced | ## The answers One block per platform and size band.
