Built an API that translates Korean cosmetic ingredients into strict INCI standards (with AI hallucination control)

Hi everyone, I’ve noticed that many developers building Shopify apps or automated tools for K-Beauty dropshippers struggle heavily with ingredient translation.

General translation tools (like DeepL or standard Google Translate) fail here because they don't provide regulatory-compliant INCI names, which can lead to strict customs rejections in the US or EU.

To solve this specific bottleneck, I built the Legal K-Beauty INCI Translator API. Instead of dealing with messy raw text, you just send the Korean ingredients via POST, and it returns a clean, structured JSON response.

Key Features:

Strict INCI Output: Returns an array of exact INCI standard names.
Hallucination Control (Legal Safety): If an ingredient is ambiguous or untranslatable, the API strictly refuses to guess and outputs "UNVERIFIED_MANUAL_CHECK_REQUIRED".
Extra Data: Automatically returns a Boolean for is_vegan_friendly and a general hazard_score.

It's officially hosted on RapidAPI, so you can test the endpoint immediately without setting up a new billing account.

If you're building e-commerce software in the K-Beauty niche, I’d love to hear your feedback on the JSON structure or any additional data fields you might need!
