Visa Introduces AI-Powered Payment Tool: Complete Transactions with a Command Line

2 hours ago

On March 19, Visa’s Crypto Labs launched a command-line tool (CLI) that lets AI agents initiate automated payments directly in the terminal—enabling "hands-free" programmatic transactions. This tool delivers payment capabilities for robots, scripts, and other automated processes without requiring API key management. It can be used to purchase cloud resources, call API services, and facilitate machine-to-machine payments. The product is currently in testing and requires users to apply for access via a GitHub account. Visa noted that as AI shifts from "answering questions" to "performing tasks"—including automated computing power purchases, service invocations, and micropayments—payment infrastructure needs to evolve to support "command-line commerce." Additionally, Visa has integrated the Machine Payment Protocol (MPP) and is collaborating with industry-led AI payment standards (spearheaded by firms like Coinbase and Cloudflare) to accelerate the development of AI-native payment ecosystems.

Visual Guide to the recent SEC Report: Why Allow Nasdaq to Trade Tokenized Stocks?

On March?19, the U.S. Securities and Exchange Commission (SEC) officially approved a Nasdaq rule change this morning—greenlighting the trading of tokenized securities on the exchange, a critical step for traditional capital markets toward blockchain technology. Under the plan, eligible stocks and ETFs will clear and settle via the existing trading system as on-chain tokens, with the same order book, trading priority, and shareholder rights as traditional securities. The pilot is tied to the Depository Trust & Clearing Corporation’s (DTCC) tokenization initiative: investors may opt for tokenized settlement when placing orders, and the system will handle on-chain processing post-trade. Nasdaq noted that beyond the settlement method, trading rules, market data, fee structures, and regulatory oversight will remain unchanged. Tokenized securities will also be fully integrated into existing U.S. securities law frameworks. For additional details, see the accompanying infographic.
