Provides a single MCP endpoint for 90+ tools across 42 backend servers (search, legal, domain, etc.) with per-call credit billing and a single API key.
Enables MCP clients to access all endpoints of an x402 gateway by paying real-time microtransactions (USDC on Base) per API call, with automatic tool discovery and spend guardrails.
A gateway that forwards tool calls to downstream MCP servers, handles x402 payment challenges with automatic wallet payment, and supports compliance checks.
