3 months since my agentic payments map. What moved: → Open USD went live, with $1B+ launch liquidity → Google opted US Shopify stores in to agent checkout (UCP) → Stripe now sits on both ACP and UCP → x402, minus wash trading and tests: ~$15M real volume

Tomorrow in Prague: @KB_SmartSol Crypto & Banking Breakfast. The question: Do agents need stablecoins, or can cards do the job? My take: both, for different flows. The hard part is the trust layer in between. luma.com/1keliaz1

x402 & MPP let you pay per API call with crypto — no account, no key. I tested both for real. They work. But ~7x slower per call than a plain key (small sample, not a rigorous benchmark). Not a speed win — built for agents that show up with a wallet and nothing else.

"Agentic payments" isn't one market. It's three: commerce, machine payments, treasury — different protocols, different rails, different rivalries (ACP vs UCP, Visa vs Mastercard). 98.6% of machine-native micropayments already settle in USDC. Full map: zdne.org/articles/agentic-pa…

In a few hours I'm joining O'Reilly's API Superstream to talk about what's actually live vs. what's still hype in agentic commerce — x402, UCP, ACP, and why B2B is where the real money is moving, not the chatbot checkout demos. Free to join, 11am ET: bit.ly/49VKu25

Mastercard's paradox: Building agentic commerce rails for the future that could make them irrelevant. If agents can route payments anywhere, the Mastercard is an option, not a necessity. Their trust layer is a self-preservation dressed as innovation. finance.yahoo.com/video/stab…

B2B agentic commerce loop is almost closed. Agentforce: seller side. Quotes, negotiates. SAP: buyer side. Evaluates bids, selects winner. MS Dynamics: execution side. Reroutes supply chains. No human. Nobody has connected them yet. That's the $2–5T question.

When humans stop searching — who controls what agents find? If your catalog isn't agent-readable, you're not losing the bid. You're not in the room. Google sees this clearly. UCP isn't just a checkout protocol. It's Google making sure it stays the front door of the internet.

Drama is unfolding in agentic commerce. And it's 1:0 for merchants. OpenAI's Instant Checkout: killed March 2026. Merchants refused to become ghost kitchens — invisible fulfilment behind OpenAI's brand. Google: Ulta: all in. Gap: refused. Same protocol. Opposite philosophy.

Today's protocols — ACP, UCP, x402 — are AI-assisted. A human clicks, agent helps. What's coming is AI-executed. The agent decides. The agent pays. Nobody clicks. Three steps. Zero humans. Different category entirely. [4/12] #UnBundled #AgenticCommerce youtu.be/veINk-Qnu8Y?si=8beO…

'25 was year zero for agentic commerce. Most of fintech didn't notice. 3 protocols. 6 months. AI agents can now transact autonomously. Fintech was debating open banking. The protocol layer got built around it. [2/11] #UnBundled #AgenticCommerce

Fintech spent 15 years making payments faster for humans. That assumption just broke. My keynote on agentic commerce at #UnBundled 👇 luma.com/znvxfc7d

10% agentic AI reliability? That’s not production-ready. That’s a demo. superface.ai/blog/agent-real…
