This one is the harder one: what I learned, what I got wrong, and the part of the build that's actually portable. If you're sitting on a data feed and wondering whether you can monetize it directly to AI agents — this is for you. The Build Pattern Strip the domain off Signal and what's left is a five-step pipeline anyone with a useful data source can run: public/private data source ↓ (GitHub Actions cron) Claude — parse + summarize + classify ↓ Supabase — idempotent storage, keyed on source URL ↓ MCP server — hosted on Vercel, exposes tools ↓ (x402 middleware) USDC payments on Base mainnet — no API keys, no accounts That's it. Five layers. Each one is independently swappable. The cron can be GitHub Actions, AWS EventBridge, a hosted scheduler — whatever. The parser doesn't have to be Claude. The store doesn't have to be Supabase.…
