Build and deploy pay-per-request services. Integrate micropayments. Create the next generation of digital commerce.

What is Nova402?

Nova402 is building x402 protocol infrastructure for the emerging API economy and beyond. Every API call becomes a micropayment transaction, enabling true usage-based pricing with instant on-chain settlement.

Core Principles

Usage-Based Pricing

Pay exactly for what you consume. No monthly fees, no commitments. Just pure value exchange per request.

Frictionless Testing

Explore and test any service before spending a single token. Validate integration before commitment.

Instant Settlement

Payments settle in under a second on-chain. No chargebacks, no disputes, complete transparency.

Multi-Chain Native

Built for a multi-chain future. Deploy once, transact everywhere:

Base

Solana

Polygon

BSC

Sei

Peaq
