What is the SentEdge AI x402 Bazaar explorer ?

The SentEdge AI x402 Bazaar explorer is an aggregated human readable discovery layer of the x402 protocol, offering a machine-readable, searchable catalog of payable APIs, blockchain services, and developer endpoints. It empowers developers, AI agents, builders, and product teams to programmatically discover available services, inspect pricing, understand input/output schemas, and seamlessly integrate pay-per-use functionality into applications.

Designed for the modern Web3 and AI ecosystem, the x402 Bazaar helps bridge the gap between service discovery and automatic payment execution. Rather than navigating disparate docs or manually searching for APIs, developers can query the Bazaar endpoint to uncover resources, explore metadata, and build experiences that leverage decentralized micro-payments using USDC and other supported currencies.

Why It Matters

Traditional API directories list services, but they do not provide a programmable way to discover pricing, enforce payment requirements, or return structured schemas for integration. The x402 Bazaar functions as a dynamic directory and API catalog that returns not only resource URLs, but also machine-friendly metadata including payment conditions, accepted payment methods, and usage patterns — all in a consistent format.

How It Works

Developers and systems can query the discovery endpoint using a simple HTTP GET request. The response includes essential fields like service URL, description, supported methods, and optional metadata needed to interact with a resource. Combined with the x402 payment flow, this allows for intelligent agent-driven discovery and usage of services without manual lookup.

    curl "https://api.cdp.coinbase.com/platform/v2/x402/discovery/resources" \
      -H "Accept: application/json"
      

The response returns a JSON array of available resources along with metadata, which your application can render, filter, or store for further use.

Use Cases

• AI agents discovering payable APIs for real-time data and compute
• Developers integrating third-party web3 services with pricing metadata
• Marketplaces aggregating APIs with micro-payment support
• Tools that dynamically generate SDKs based on service schemas

With rich metadata and a consistent discovery interface, the x402 Bazaar enables a new generation of composable, pay-per-use services — perfect for AI-powered applications, data fetchers, or any developer seeking a programmable marketplace of APIs.
