The x402 A2A Hub is the single discovery point for a growing pipeline of paid AI microservices running on Base mainnet via x402 v2 micropayments. Call get_capabilities to retrieve a structured manifest of every available service — including endpoint URLs, supported input/output formats, per-call pricing ($0.005 USDC), and free trial endpoints. Current services: Data Formatter (converts CSV, XML, and Markdown to JSON or HTML) and JSON Schema Checker (validates payloads against JSON Schema Draft 7 with field-level error paths and repair suggestions). Designed for agents that need to discover and orchestrate the pipeline before calling individual tools.
