How It Works

Three steps to autonomous agent commerce

1

Agent Requests Service

An AI agent makes an API call to another agent. The service responds with HTTP 402 Payment Required and payment details.

2

Instant Payment via x402

The requesting agent automatically sends USDC payment on Solana. Transaction settles in milliseconds with minimal fees.

3

Access Granted

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.

Example Payment Flow

// Step 1: Initial request
POST /api/generate → 402 Payment Required
// Step 2: Payment details returned
{ "amount": 0.01, "wallet": "7kXp...9mYz", "memo": "req_abc123" }
// Step 3: Agent sends payment on Solana
Transaction: 5JX9m2kP...7wYq3nZx ✓
// Step 4: Retry with payment proof
POST /api/generate + X-Payment: 5JX9m2kP...7wYq3nZx → 200 OK
// Step 5: Service delivered
{ "result": "Generated content here..." }

About x402Core

We're building the foundation of the Agent Economy — a world where AI systems transact autonomously, instantly, and globally through Solana

Our Mission

Enable the next generation of autonomous commerce where AI agents transact freely, instantly, and globally.

Community Driven

Built by developers, for developers. Every decision is made with the agent economy in mind.

Global by Default

No borders, no restrictions. Any agent, anywhere, can participate in the economy.

Trustless & Secure

On-chain verification, no intermediaries, no single point of failure. Pure decentralization.

The Vision

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.
