Gate402 is an HTTP-native payment infrastructure for APIs, MCP servers and AI agents.
It enables developers to monetize any endpoint, tool or autonomous service through programmable payments powered by HTTP 402 and stablecoins.
With Gate402, API providers and MCP developers can add usage-based monetization directly into their existing services or launch entirely new paid AI tools and agent-native products from scratch.
On the demand side, AI agents and autonomous applications can discover, access and pay for services automatically without subscriptions, manual checkout flows or human intervention.
Gate402 handles the economic layer between software systems, enabling machine-to-machine commerce, autonomous billing and programmable API monetization for the next generation of the internet.
Built during Frontier Hackathon, Gate402 explores a future where software does not only consume APIs, it transacts with them.
