PackageGuard is answering right now. Last checked 5 min ago. It exposes 1 tools.
x402-gated safety checker for npm/PyPI packages before you npm install / pip install.
The linked repository no longer exists on GitHub — it was deleted or made private.
Everything else answered, so this is steady rather than shaky. We check every 15 minutes, which is how a one-off gets told apart from the start of a pattern, and how you hear about the next one within the hour instead of from your users.
Endpoint below is the one we actually reach during checks — not the one copied from a README. Last verified 5 min ago.
