A landmark proof‑of‑concept for AI‑initiated payments

On July 2, 2026, Nuvei – the global fintech that provides end‑to‑end payment infrastructure – announced the successful completion of a live agentic‑commerce trial in partnership with Visa, German‑based Arvato Systems, and fashion retailer Kings and Priests. Conducted from Montreal, the experiment demonstrated that an AI‑powered merchant agent could autonomously select a product, initiate a purchase, and settle the transaction entirely within the agent, without redirecting the shopper to a separate checkout flow.

The transaction was processed on live Visa rails using a tokenized Visa credential under the Visa Intelligent Commerce framework. Multiple European issuers, including Alpha Bank, Piraeus Bank, Bank Leumi, CAL, MAX, and Bank of Cyprus, participated, confirming that the model works across a diversified issuer landscape. The proof‑of‑concept also highlighted that shopper‑defined guardrails—such as spend limits and category restrictions—remained enforceable throughout the process.

From discovery to execution: What the trial proved

Historically, AI has been employed primarily for product discovery and recommendation. Nuvei’s demonstration pushes the boundary by embedding the full payment flow inside the AI agent, a capability the company labels “first‑party agentic payments.” In the test, the AI agent acted as a trusted intermediary, handling both the authorization and settlement stages without handing off the transaction to a traditional payment gateway.

Nuvei describes the underlying technology as a protocol‑agnostic execution layer that any AI agent can invoke. This layer abstracts the complexities of differing payment standards, allowing agents to interact with Visa, Mastercard, or other networks through a single, unified interface.

“Agentic commerce is the next evolution of digital commerce, with AI not just finding products but initiating purchases,” said Phil Fayer, Chair and CEO of Nuvei. “This proof of concept starts inside a merchant’s own experience and points to where payments are heading: a layer that lets any agent, on any protocol, make a payment.”

Technical underpinnings: Protocol Compatibility and Know‑Your‑Agent

Nuvei’s architecture rests on two foundational components:

• Protocol Compatibility Layer – Merchants integrate once and gain the ability to accept payments from agents adhering to any of the emerging standards, namely ACP, AP2, or MCP. The layer routes transactions across networks, with Nuvei planning certifications for both Visa Intelligent Commerce and Mastercard Agent Pay.
• Know Your Agent (KYA) – This governance framework registers and credentials agents, validates consumer mandates, scores agent reputations, and ensures auditability. By extending identity verification beyond the consumer to the agent itself, KYA addresses a key risk vector that has traditionally limited widespread adoption of AI‑driven payments.

Together, these modules promise a single integration point for merchants, eliminating the need for multiple, network‑specific adaptations.

Market signal: Merchant demand drives the roadmap

During Nuvei’s Global Customer Advisory Board meeting earlier this week, participating merchants emphasized the immediate need for first‑party agentic capabilities. They argued that while public, third‑party agents may become relevant as the market matures, the priority is to empower merchants with direct control over AI‑initiated purchases today.

“This proof of concept shows how the payments ecosystem can enable AI‑driven purchasing while preserving trust, control, and transparency,” said Carsten Bruning, Vice President Digital Commerce at Arvato Systems. “With Visa and Nuvei, we validated interoperability across the flow and proved that payment can complete inside the agent rather than on the merchant site.”

The sentiment aligns with broader industry forecasts that anticipate $1 trillion in global agentic transaction volume by 2030, swelling to $3–5 trillion by 2035, according to McKinsey. If the technology scales, it could reshape the economics of digital retail, shifting the point of purchase from the consumer’s browser to the merchant’s AI layer.

Issuer and network perspectives: Extending existing tokenization

Visa’s Head of Product & Solutions for Europe, Mathieu Altwegg, highlighted that the trial leveraged existing Visa capabilities—tokenization, network‑level controls, and the newly introduced Visa Agentic Ready framework—to enable secure, agent‑initiated payments. By building on familiar infrastructure, Visa aims to reduce friction for issuers adopting the model.

“Through Visa Agentic Ready, we are extending existing capabilities — including tokenization and network‑level controls — to enable agent‑initiated payments in a trusted and consistent way,” Altwegg explained.

The participating issuers confirmed that the tokenized Visa credential functioned seamlessly across their internal risk and fraud engines, suggesting that the approach can be retrofitted into current issuer workflows without wholesale system overhauls.

Merchant‑centric benefits and risk considerations

From a merchant’s viewpoint, the ability to keep the entire transaction inside a proprietary AI agent offers several advantages:

• Data continuity – Transactional data remains within the merchant’s ecosystem, facilitating richer analytics and tighter personalization loops.
• Brand consistency – Customers experience a seamless flow that aligns with the merchant’s UI/UX, avoiding the disjointed feel of third‑party checkout redirects.
• Risk mitigation – By enforcing spend caps and category filters at the agent level, merchants can pre‑empt fraudulent or out‑of‑policy purchases.

However, the model also introduces new risk vectors. The “Know Your Agent” component must reliably assess agent reputation and enforce mandates, especially when agents evolve from proprietary to public ecosystems. Nuvei acknowledges that “the hard part isn’t the transaction; it’s carrying a verifiable mandate, managing real‑world agent risk, and clearing across any rail,” echoing Fayer’s assessment that the challenge is fundamentally a platform problem rather than a feature add‑on.

Roadmap: From sandbox to production

• Full protocol compatibility across ACP, AP2, and MCP.
• A KYA registry and associated risk‑scoring mechanisms.
• Network certifications for both Visa Intelligent Commerce and Mastercard Agent Pay.
• A developer sandbox that mirrors Nuvei’s Level 1 PCI‑certified infrastructure, complete with existing fraud‑management tools.

By leveraging its existing “Every Payment, Everywhere” platform, Nuvei aims to deliver the new functionality without requiring merchants to redesign their payment stacks.

Analyst take: Competitive positioning and strategic implications

The demonstration positions Nuvei as a front‑runner in the nascent agentic‑commerce space, a niche that sits at the intersection of AI, payments, and identity management. Competitors such as Stripe and Adyen have hinted at AI‑enabled checkout experiences, but none have publicly showcased a live, tokenized, multi‑issuer transaction that remains fully inside an AI agent.

If the technology gains traction, it could accelerate the convergence of embedded finance and digital commerce, prompting regulators to revisit mandates around consumer consent and agent accountability. The KYA framework may become a de‑facto standard for verifying AI agents, much like KYC remains central to customer onboarding.

Outlook: From proof‑of‑concept to industry standard

The successful trial underscores a clear market appetite for AI‑driven, in‑agent payments. As merchants seek to differentiate through frictionless experiences, the ability to embed purchase initiation and settlement within a trusted AI layer could become a competitive necessity. Nuvei’s roadmap, combined with Visa’s network support and the involvement of reputable European issuers, suggests that the ecosystem is ready to move beyond pilot projects.

Future milestones will likely include:

• Expansion of participating issuers beyond Europe to North America and APAC.
• Integration with additional payment networks, notably Mastercard’s Agent Pay.
• Development of industry‑wide standards for agent authentication and mandate verification.

For now, the collaboration between Nuvei, Visa, Arvato Systems, and Kings and Priests offers a tangible glimpse of how AI could reshape the very mechanics of digital commerce.
