Show HN: I built a BYOK AI gateway after a 100x Cloudflare KV cost mistake

I run a small data recovery business in Japan, and over the past year I've been building with AI coding tools like Claude Code, Cursor, and Cline. One of my side projects is an overnight content pipeline for my business. It pulls RSS feeds, fetches source articles, generates posts with AI, scores them, and publishes them to WordPress without supervision. The content is a bit niche: cybersecurity incidents for Japanese manufacturing companies in Aichi Prefecture - Toyota's home region - where older workflows like fax and password-protected ZIPs still haven't fully disappeared.
