Payments disappear into apps

A credit card checkout used to be a separate room on the internet, with its own forms, redirects, and fraud checks. In 2025 and 2026, companies started moving the cash register inside the app itself, so the payment happens in the same flow as the chat, the code, or the shopping cart. (base.org) Shopify’s stablecoin rollout is the cleanest example of that shift. Since June 12, 2025, eligible Shopify Payments merchants have been able to accept United States Dollar Coin on Base without adding a new gateway, and customers can pay from supported crypto wallets in guest checkout or Shop Pay. (shopify.com) Base then wrapped that rail in its own checkout layer. Base Pay says it works on stores running Shopify Payments, settles purchases with simple biometric confirmation, and advertises 1 percent back at Shopify stores while unspent United States Dollar Coin keeps earning yield in the wallet. (base.org) That changes what “paying” feels like. Instead of typing card numbers into a web form, the app can treat money more like a permission prompt, where you approve once with Face Identification or a fingerprint and the purchase completes inside the same screen. (base.org) Razorpay is pushing the same idea from the other direction, starting with software and chat interfaces rather than online stores. Its Agentic Payments product says businesses can enable in-chat transactions, in-app artificial intelligence checkout, and voice-based purchases while authentication and compliance stay in the background. (razorpay.com) Razorpay has also built a Model Context Protocol server so artificial intelligence tools can call Razorpay payment application programming interfaces directly. Its documentation says the server is designed to connect Razorpay’s payment stack to artificial intelligence clients, which is the plumbing needed for an assistant to create or confirm a payment without sending a user to a separate billing page. (razorpay.com) By October 9, 2025, Razorpay, the National Payments Corporation of India, and OpenAI said they were piloting agentic payments on ChatGPT in India. The announcement described a system where artificial intelligence helps people discover, choose, and pay for products in one conversational flow. (razorpay.com) A second piece of the story is charging for tiny actions instead of full subscriptions. PayAI’s documentation describes x402 as infrastructure for pay-per-use application programming interface transactions between agents, which means a model, bot, or app can pay for one call at a time instead of signing a monthly contract first. (docs.payai.network) PayAI’s facilitator docs spell out the machine-level version of that. A client sends a request, a resource server states the price, and a facilitator server verifies the payment payload and executes settlement, so the payment check can happen in the same request that asks for the result. (docs.payai.network) The company says this is already moving beyond demos. PayAI’s ecosystem page lists more than 25 integrated projects, more than 35 million transactions processed, and average settlement under one second for usage-based payments across apps and artificial intelligence agents. (payai.network) Put those pieces together and the old checkout page starts to look like an interruption rather than a destination. Shopify turns stablecoins into a built-in option, Base turns that option into a one-tap consumer flow, and Razorpay and PayAI are building the rails for software agents to buy things and bill each other inside the same conversation or application programming interface call.
