Attestari's verdict on an npm or PyPI package version, asked before an agent installs it.
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 8 min ago.

This one needs environment variables set before it will start:
ATTESTARI_API_KEY (An Attestari API key (att_live_...), Developer tier and above).
The author declared them in the registry entry; get the values from the project itself.
This endpoint answered with an authorization challenge. The server is running, and it signs you in through your browser: there is no API key to paste.
