x402-streamsocket solves the gap between real-time usage and real-time payment.

Most live systems today serve users continuously but charge them discretely. Once a WebSocket connection is open, there’s no native, trust-minimized way to guarantee the user is still paying while consuming resources. Payment usually happens before or after usage, not during it.

This creates real problems:

Overpayment: Users pay upfront even if they disconnect early.

Underpayment risk: Services keep connections open without knowing if payment still reflects usage.

Complex billing logic: Developers need off-chain tracking, reconciliation jobs, refunds, and abuse protection.

Poor fit for AI and agents: Autonomous systems need payment and access to stay perfectly in sync.

x402-streamsocket fixes this by making payment itself the access signal.

A Superfluid stream becomes a live proof of intent. As long as value is flowing, access continues. The moment it stops, access ends. No trust, no guessing, no cleanup
