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.
