API Gateway — 17 APIs for AI Agents

Single MCP server exposing 17 production APIs behind one public domain.

All APIs are served at https://momentumbysamay.online/api/<apiname> (DNS → 167.71.22.95), a single nginx gateway with Let's Encrypt HTTPS. The Website Intelligence bundle runs on droplet 1; Marketing, Web Scraper, PDF and Email Verify are reverse-proxied from droplet 2.

🚀 What This Is

An MCP (Model Context Protocol) server that wraps 17 real, deployed APIs into MCP tools. Any AI agent with MCP support can discover, call, and pay for these APIs programmatically.

How AI Agents Use It

Connect — Agents connect via MCP (stdio or HTTP)
Discover — Agent calls list_tools() → sees 20 tools
Pay — Agent calls generate_invoice + check_balance for crypto payment
Use — Agent calls any API tool, credits auto-deduct
