Sentinel API - AI-powered API security. 21ms latency. One header.

Hey Product Hunt! 👋 I built Sentinel API because I was tired of static WAFs that block legitimate traffic and miss real threats. What it does: • Analyzes every API request for XSS, SQLi, SSRF, etc. • Returns a security decision in 21ms • Integrates with ONE header — no SDKs, no complex configs How I built it: • NestJS + PostgreSQL + Redis on Railway • Next.js landing on Vercel • AI-assisted development (yes, AI helped code this!) Free tier: 1,000 requests/min — generous enough for production side projects. For the PH community: First 20 people to upvote + comment "SENTINEL" get 30 days of Pro free.
