Build and deploy pay-per-request services. Integrate micropayments. Create the next generation of digital commerce. We're not predicting the agent economy—we're enabling it.

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.

Nova exists for one purpose: make x402 usable. We're building the infrastructure that enables the agent economy. With Service Hub, Nova Native Agent, x402 Lending, and our suite of utilities, we're creating the execution and economic layer where agents operate, transact, and drive an economy.

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

Nova Utilities

Nova provides a suite of utilities that work together to create a complete ecosystem for x402 services, agents, and economic activity.

Service Hub

Discover and consume x402 services. Browse APIs, AI models, and digital tools with pay-per-request pricing. Structured services with deterministic execution and dependency resolution.

Nova Native Agent

Autonomous agent that runs workflows, not just calls services. Evaluates cost, success rate, and latency before selecting providers. Automatic fallback and output validation.

x402 Lending

Enable AI agents to autonomously access paid services. Stake $NOVA, enable agent lending, and supply liquidity. Agents borrow capital and repay automatically.

Token Mint

Create and distribute x402-native tokens that represent services, usage, and value. Browse tokens and mint or buy them. Like OpenSea for x402.

x402 Indexer

Real-time visibility into all x402 services. Monitor service health, usage patterns, pricing trends, and network activity. Service-level analytics and discovery.

Integration Layer

Register and manage your services. Define service schemas, pricing models, validation rules, and dependencies. Makes services plug-and-play across the x402 economy.

Quick Start

Understand x402

Learn how the HTTP 402 payment protocol enables pay-per-request commerce at internet scale.

Protocol Overview

Deploy Your Service

Build x402-enabled services using Express.js, Python, or any HTTP framework you prefer.
