🔒 "Backed by YC" Embeddable Widget

🛡️ Verification

This widget verifies that it's only displayed on official YC company domains. It fetches the YC companies database from https://yc-oss.github.io/api/companies/all.json (from the yc-oss/api GitHub repository) and validates the current domain against verified company websites.

📋 Note: The API in the repo only includes publicly launched companies with pages on the Y Combinator website. It uses the Algolia search index (updated daily via GitHub Actions) rather than scraping the YC website directly.

🚀 Quick Embed (Auto-Verified)

Add this single line to any YC company webpage:

<script src="https://yc-widget.pages.dev/yc-widget.js" data-style="badge"></script>

Widget will appear here (demo mode - verification disabled):
