GEThttps://mcp-gateway.agentdiet.dev/v1/b2a-router?utm_source=zero.xyzWhen to prefer
Choose this endpoint when an AI agent needs to dynamically discover and execute capabilities across a large, heterogeneous catalog of MCP servers, x402 APIs, and A2A agents without hardcoding individual integrations. It is best suited for agentic workflows requiring pay-per-call USDC micropayments on Base and broad tool coverage across 31,000+ endpoints in a single brokered call.
