Q4 2026How It Works
No accounts. No billing dashboards. Payment and data delivery happen in the same request-response cycle.
Any client — AI agent, app, or human — sends a standard HTTP GET or POST to an x402-enabled endpoint.
The server replies with payment details: amount, currency (USDC), destination wallet, and network (Base or Solana).
The agent signs and submits an on-chain stablecoin transaction. No human clicks. Settles in under 0.5 seconds.
The agent resubmits with an X-PAYMENT header. The facilitator verifies on-chain and the server delivers the resource.
