Newborn Town, a Hong Kong-based global social entertainment company, launched NUSD Pay on April 21. The system uses the x402 protocol to move payment settlement from application-layer APIs down to the HTTP protocol layer, allowing AI agents to complete transactions automatically, according to the company’s announcement.
The core system is already in commercial operation and claims to reduce cross-border transaction costs by more than 70% compared to traditional payment solutions.
How x402 Works
The x402 protocol leverages the HTTP 402 “Payment Required” status code, a response code that has been defined in the HTTP specification since the 1990s but never widely implemented. NUSD Pay uses it as a trigger: when an AI agent calls a service or executes a task, the server responds with a 402 status code, and the agent automatically completes payment settlement like making an API request. No manual authorization per transaction.
This design means agents can pay for API usage, data access, computing resources, and content without a human approving each charge. The payment happens at the same layer as the HTTP request itself.
OpenClaw Integration
NUSD Pay has completed initial deployment of AI Skills on the OpenClaw platform. Users can already query NUSD Pay product information and API documentation through natural language interaction via OpenClaw.
The company plans to expand these Skills to include data inquiries, automated reconciliation, wallet address creation, and backend management. The first phase serves Newborn Town’s own global business ecosystem across MENA, Southeast Asia, Latin America, and Europe. Enterprise B2B and B2C solutions will follow.
A Crowded Week for Agent Payments
NUSD Pay is the third major agent payment infrastructure announcement in a week. MetaComp launched its Know Your Agent (KYA) governance framework at Money20/20 Asia, and Ant Digital Technologies proposed a blockchain-based 4R Full-Stack Architecture at Hong Kong Web3 Festival on April 20. Each approaches the same problem differently: MetaComp focuses on compliance and identity governance, Ant on blockchain-native settlement and agent identity, and Newborn Town on protocol-layer simplicity.
The convergence suggests the “how do agents pay for things” question has moved from theoretical to urgent. The project lead told PR Newswire that the move is “primarily driven by the long-term development needs of the company’s global operations,” noting that “an increasing number of commercial activities may eventually be completed autonomously by AI systems.”
