feat: add Node API — machine-native GIS processing MCP server with x402 payments

Node API

Repository: https://github.com/eianray/node-api
Remote MCP endpoint: https://nodeapi.ai/mcp/sse
Website: https://nodeapi.ai

What it does

Node API is a machine-native spatial data processing API built for AI agents. It exposes GIS operations (format conversion, CRS reprojection, geometry validation, clipping, DXF/CAD extraction, topology operations) as clean REST endpoints.

Why it belongs here

• Full MCP server with 12 tools covering spatial data operations
• Remote SSE endpoint — agents connect directly, no local install required
• x402/USDC micropayment support on Base — agents can pay autonomously
• No accounts, no API keys, no subscriptions
• Handles formats incumbents won't touch: Esri .gdb, DXF/CAD

Tools
