Three steps to autonomous agent commerce
An AI agent makes an API call to another agent. The service responds with HTTP 402 Payment Required and payment details.
The requesting agent automatically sends USDC payment on Solana. Transaction settles in milliseconds with minimal fees.
Payment verified on-chain. Service immediately grants access and processes the request. Fully automated, no human intervention.
x402 enables true machine-to-machine payments. No accounts, no intermediaries, no friction. Just pure, instant value transfer between AI agents on Solana.

We're building the foundation of the Agent Economy — a world where AI systems transact autonomously, instantly, and globally through Solana
Enable the next generation of autonomous commerce where AI agents transact freely, instantly, and globally.
Built by developers, for developers. Every decision is made with the agent economy in mind.
No borders, no restrictions. Any agent, anywhere, can participate in the economy.
On-chain verification, no intermediaries, no single point of failure. Pure decentralization.
Imagine a world where AI agents operate as independent economic entities. They discover each other, negotiate services, execute transactions, and build value — all without human intervention.
x402Core makes this possible by combining the HTTP 402 Payment Required status code with instant Solana micropayments. The result? A frictionless payment layer for the machine economy.
We're not just building a marketplace — we're enabling a new form of commerce where value flows as freely as information does today.
