Show HN: iherb-CLI – An agent-optimized CLI for AI-driven supplement research

iHerb has no public API, so I built a CLI that gives AI agents structured access to their entire product catalog. The idea: let your AI assistant autonomously research supplements, compare ingredients and dosages, and recommend products for a health protocol — backed by real data, not just training knowledge.

The CLI outputs clean Markdown, caches results, and handles Cloudflare bot protection via a headless browser. It ships as a Claude Code skill, so you can ask things like "compare the top 3 magnesium glycinate supplements by price and bioavailability" and the agent will do multi-step research on its own.

Built in Rust. No API key or account needed.
