The SentEdge AI x402 Bazaar explorer is an aggregated, human-readable discovery layer for the x402 protocol — 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 services, inspect pricing, understand input/output schemas, and seamlessly integrate pay-per-use functionality into applications. Designed for the modern Web3 and AI ecosystem, it bridges the gap between service discovery and automatic payment execution using USDC and other supported currencies.
Traditional API directories list services, but don't provide a programmable way to discover pricing, enforce payment requirements, or return structured schemas. The x402 Bazaar is a dynamic directory that returns resource URLs plus machine-friendly metadata — payment conditions, accepted methods, and usage patterns — in a consistent format.
Developers and systems can query the discovery endpoint with a simple HTTP GET. The response includes service URL, description, supported methods, and the metadata needed to interact with a resource. Combined with the x402 payment flow, this enables agent-driven discovery 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.
Discover payable APIs for real-time data and compute.
Integrate third-party web3 services with pricing metadata.
Aggregate APIs with built-in micro-payment support.
Generate SDKs dynamically from 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.
