Wu Blockchain learned that Visa and Artemis jointly released a report stating that AI Agents have begun autonomously booking travel, purchasing computing power, and calling data services, and that machine payments are moving from concept into real commercial scenarios. Since going live in May 2025, x402 has completed about 109.6 million transactions, with adjusted transaction value of about $15 million. The average payment per transaction on the protocol is less than 1 cent, and fixed fees from traditional bank cards lack economic viability for such micro-payments. In the future, bank cards may continue to handle routine e-commerce payments, while stablecoins are more suitable for high-frequency machine payments; the biggest current obstacle is not settlement technology, but rather that the authorization of AI Agents, responsibility allocation, and dispute resolution mechanisms have yet to be clearly defined.
