Service Hub
Discover and consume x402 services. Browse APIs, AI models, and digital tools with pay-per-request pricing.
Overview
Service Hub is Nova's marketplace for x402-enabled services. Every service defines pricing, accepted currency, and validation rules directly in x402 format. Services are no longer static endpoints—they become monetizable, verifiable, and composable units of work.
The Hub introduces a service execution runtime for x402. Requests are executed through a deterministic engine that returns structured output, eliminating loose JSON blobs. Services can reference other services internally through dependency resolution, enabling composable workflows.
Key Features
Structured Pricing
Every service defines pricing, accepted currency, and validation rules directly in x402 format. No ambiguity, no guesswork—clear pricing models for every service.
Deterministic Execution
Requests are executed through a deterministic engine that returns structured output. No more loose JSON blobs—predictable, validated responses every time.
Dependency Resolution
Services can reference other services internally, enabling composable workflows. Build complex multi-step operations by chaining services together.
Service Discovery
Browse AI services, APIs, and tools from builders worldwide. Filter by category, pricing, network, and service type. Find exactly what you need.
How It Works
Browse Services
