About x402
Against the backdrop of a rapidly expanding stablecoin market and Japan’s progressive regulatory tailwinds, x402 is fundamentally rewriting the economic fabric of the internet. Since its inception in 1997, the HTTP 402 (Payment Required) status code remained dormant due to a lack of native payment infrastructure. Today, with the arrival of the x402 protocol, it is finally seeing its “mainnet moment.” This is more than just a payment feature; it is establishing itself as the Standard Value-Exchange Protocol for the Web3 era, enabling every API and digital resource to monetize content delivery instantaneously.
AI Agent Economy × x402
The most significant paradigm shift triggered by x402 is the emergence of the AI Agent Economy. We are moving beyond human-centric transactions toward a world where autonomous AI agents manage their own wallets, interacting with 402 responses to settle payments in milliseconds to access data and services. This is no longer sci-fi. x402 is seeing explosive, utility-driven growth: transaction volume skyrocketed 10,000% in a single month, now processing over 500,000 transactions weekly.
About us
Today, the x402 ecosystem is fortified by a powerhouse network of over 40 strategic partners, including global infrastructure leaders like Cloudflare, AWS, and Anthropic. Builders are rapidly shipping MCP (Model Context Protocol) servers and marketplace primitives, integrating AI models into the transactional layer of the internet.
By expanding its cross-chain footprint across Solana, Base, and Polygon, x402 is transcending being just a protocol to become the new standard for internet-native payments. In a future defined by the autonomous intersection of digital assets and AI, x402 will serve as the premier pipeline bridging the Japanese market with the global on-chain economy. We are committed to accelerating this transition and scaling the infrastructure of tomorrow.
