Is Know Your Agent (KYA) Really Necessary?

Is “Know Your Agent” (KYA) Really Necessary? The tale of an Orphan Signal

Short Blog | June 2026

A new category of startup has emerged around “Know Your Agent” (KYA) — the idea that merchants and payment platforms need a framework to verify the identity, authority, and auditability of AI agents acting on behalf of consumers. PYMNTS has covered the space extensively, and KnowYourAgent.xyz is already pitching merchants on “identity, policy controls, and evidence for every AI-agent transaction at checkout.” The framing is intuitive: if a bot is buying something, shouldn’t you know who sent it?

I want to push back — not on the problem, but on whether KYA, as a standalone service category, is the right solution.

Carts and Mandates: Decoupling Discovery, Authentication, and Liability 

Executive Summary

I just got back from 2 weeks of vacation and catching up on all that transpired. No one reads this blog for its technical depth, but a few browse it for the economic implications and power struggles going on behind the scenes (hence “inside baseball”).

I/O 2026 was last week (see product announcements). The Commerce team showed how Universal Cart, Universal Commerce Protocol (UCP) and Agent Payments Protocol (AP2) would drive a frictionless revolution in digital commerce.  By consolidating products from Search, Gemini, YouTube, and Gmail into a single persistent cart, Google is attempting to establish itself as the default transaction and orchestration layer of the internet. While consumers would love to engage across any platform and any retailer from any device…. A universal cart is also necessary for operating across any agentic platform and “specialist”.  Agentic commerce is certainly gaining traction, but Walmart’s Rufas and Amazon’s Alexa also want to play in the game at the front end (so does Open AI)

Wallet expansion to universal cart is great for Google; however, it’s not great for everyone else, as platforms make for poor custodians (i.e., they are not neutral). Particularly when it comes to controlling credentials and measuring their own effectiveness.  My concerns here are shared by retailers, banks, processors and networks as this architecture conceals a profound structural conflict over control and economic value.  Google’s “own-it-all” will create a great customer experience, and allow them to move agentic from the current “conversational commerce to merchant checkout” state, but who wants to invest in a platform where they become disintermediated, or a dumb fulfillment pipe?

Visa CLI and X402 CONVERGENCE

Last week I wrote about MPP and x402 solving the internet’s original sin: the inability of machines to pay machines without a human in the loop. This week, Visa made that argument a lot easier to make.

Visa Crypto Labs quietly launched Visa CLI, a command line tool that gives AI agents a wallet. One npm install. One setup command. And your agent can pay for anything on the internet, charged to a real Visa card, without an API key, without a pre-funded crypto wallet, without human intervention.

I got beta access this week and tested it. Here’s what I learned, and why I think the CLI is the most important signal yet that the incumbent payment networks are serious about the agentic commerce era.

The Evolution of Checkout: Invisible, Instant, and Everything In Between

My friend Simon Taylor at Fintech Brainfood published a provocative piece this week: The Checkout is Dead, Part 2. His thesis is elegant — the future of agentic commerce is invisible. No cart. No confirmation screen. No “Pay Now” button. Just an event in the world, and money moves.

IMHO He’s right about the general direction. But he’s wrong about the scope and timeline. Not everything fits in instant, and its really important to look not only at OpenAI’s instant checkout FAILURE at Walmart, but also their internal success (ie Sparky driving 35% sales increase with internal checkout).

Owning Your Bot’s Actions: Target Part 2

In my previous post, covering Target’s “Your Bot is Your Responsibility”  was the only move they could make. When you let an AI bot loose with your credit card, you are effectively handing your car keys to a teenager; you can’t act surprised when there’s a dent in the bumper. But Target’s stance isn’t just a legal shield; it is a flare gun fired over a massive Governance Gap. Today’s agentic commerce is high on technology and standards, but dangerously low on the commercial terms that actually make markets function. To be clear, it’s not for lack of effort from V/MA, nor is it technology; it is resistance to change.

Explaining the Death of OpenAI’s Instant Checkout

Short Blog

To my regular readers, you know the flow of data within a network is complex (see Data Games). The news that OpenAI is effectively shelving its “Instant Checkout” initiative in favor of a referral-based “conversational commerce” model shouldn’t come as a surprise. While the tech press might frame this as a strategic pivot, those of us in the eCommerce trenches know it for what it is: a collision with merchant’s role in risk, costs, CX, control and their own AI dreams.

OpenAI attempted to solve its monetization problem by trying to seize control of the top of the funnel, betting that the sheer volume of consumer demand would force merchants to bow to their interface. They were wrong. They fundamentally miscalculated the power dynamics of the transaction and the complexity of the global conversion funnel, a funnel that Google understands intimately because they serve both ends of it globally (ie merchant partners).

Agentic Recap – Last Week’s Big Announcements. 

Sorry for delay.. Just had a new grandson on Wednesday, and everyone is doing fine. One quick note, if your looking for one of my old posts, or topics like AP2, try my new search. Completely rebuilt to look through my posts and all “trusted” authorities on a topic.

Exec Summary

Last week’s flurry of announcements confirmed our thesis: Agentic commerce is off to a slow start, and the “machine-to-machine” (M2M) revolution is currently a “human-in-the-loop” (HIL) reality. Despite the hype, machines aren’t autonomously settling transactions yet; they are discovery engines landing consumers on retailer checkout pages. While “lab” pilots show machine to machine transactions are technically possible – in a lab. The reality is conversational commerce, more like an enhanced search. 

Key Items covered today

  1. Agentic Hurdles are huge. Changing consumer behavior, shifting risk, economic “Gordian Knot” of value creation and pricing, Trust and Authorization, …etc. The payment piece is the “easy” party.  There will be no wholesale change in the next 2-3 years, merchants and marketplaces want to retain consumer behavior and leverage their own data, the future for most transactions will be a checkout on the merchant’s website. 
  2. Card networks are firmly established as the payment method and will retain their role as the identity infrastructure of the internet. Stablecoin is a settlement  innovation, and cards can sit on top. Visa is at least 2 yrs ahead of MA. MA’s agent pay integration to Google’s AP2 mandates is still a lab experiment that will require both Issuer and merchant approval. For example Banks will want the full intent mandate to take the risk, something neither Google nor Merchants will be keen to share. 
  3. OpenAI’s abandonment of their own wallet is very significant and a realization that merchants hold the keys in the early days of eCom, with many major merchants wanting a PAR to reference COF, not a tokenized credential where they own the risk. 
  4. Visa’s two big announcements are significant. The partnership with Bridge to issue stablecoin linked cards in 100 markets will propel a new market for cards in M2M based UCs.  “INTELLIGENT AUTHORIZATION” a universal acceptance API against different schemes and payment types, thus eliminating the need for costly infrastructure rebuilds. 
  5. When perfect authentication does happen, it will be a watershed moment for payments and every entity that provides risk services. Processors will be particularly hard hit, afterall how will processors differentiate when every payment type has 0 fraud and 100% authorization rate. Shopify and other merchant service providers (MSPs will gain significant leverage and expand their own VAS). This dynamic explains why Stripe is investing so heavily in Stablecoin, its an effort to differentiate and improve speed and a developer community in something unique.

Keeping Up With Chaos: A Payments Stakeholder Reality Check

Short Blog – Bullets

It’s getting harder to keep up with payments, a subsector that has not been great for payment investors, between the Saaspocalypse, AI, agentic commerce, stablecoins, the Genius Act, open bank charters, and COF buying Brex, we are deep into “what just happened?” era. While I see tremendous opportunities, not everyone is impacted the same (see 2025: The Great Decoupling).

You don’t read this blog for deep tech insight; you read it to understand where change is actually happening and where the money, risk, and power are moving. Today is a short recap of which stakeholders face the biggest near-term impact, where progress is being made and where investment is flowing.

UCP Enables a New Economy

Yesterday, Google’s CEO unveiled Universal Commerce Protocol (UCP) at NRF.  UCP represents a defining moment in the architecture of digital commerce; the strategic imperative is no longer merely about organizing the world’s information but about organizing the world’s commercial intent and empowering merchants to leverage their own data to construct superior customer experiences.  This shift is not incremental; it is a fundamental re-platforming of the digital economy, where Google is uniquely positioned to serve as the orchestrator within a “virtuous cycle” of interaction among retailers, consumers, and intelligent agents. 

“For many people, discovery is the fun part of shopping. Making a decision is where things get harder. As an indecisive shopper myself, I’m looking forward to the day when agents can help me get from discovery to purchase.

At Google, we’re busy laying the groundwork for this agentic ecosystem to work well. That includes building a common language for these systems and services to talk to each other.

As a next step we are introducing the Universal Commerce Protocol (UCP), designed for the era of agentic commerce. It was built to meet the needs of retailers AND customers, keeping the full customer relationship front and center — from the moments of discovery to decision and beyond”. – Sundar Pichai NRF – Jan 11 2026

AP2 as Merchant Signals – 4 Scenarios 

Today I’m outlining three near-term scenarios (24 months) for how AP2 signals will work in agentic commerce. Per my blog last week, AP2 is the agentic payment scheme with the most momentum (160+ partners), but in the immediate term (2026–2027), it will operate primarily in a “signals” metaphor for 3 main reasons:
