Nothing serious here today

Today is the operative word: we check SciX / NASA ADS every 15 minutes and re-read its code on every release. Watch it and you find out the day that stops being true.

Put your own value in place of <SCIX_API_TOKEN> (SciX / ADS API token from https://ui.adsabs.harvard.edu/user/settings/token). The author’s registry entry marks it as required.

SciX / NASA ADS — questions

Answers built from our own checks of this server.

Why is there no uptime for SciX / NASA ADS?

SciX / NASA ADS runs on your own machine over stdio — there is no network address to reach, so uptime cannot be measured for it by anyone. What can be measured is adoption: the pypi package scix-client was installed 182 times last week.

How do I connect SciX / NASA ADS?

Copy the ready config from this page. We generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each in the form that client actually reads. It runs locally, so the command pulls scix-client straight from pypi; nothing to host, nothing to sign up for.

How many people use SciX / NASA ADS?

The pypi package scix-client was installed 182 times in the last week. Week over week that is -86%. We show installs rather than GitHub stars on purpose: a star is a bookmark, an install is someone actually running it.

Is SciX / NASA ADS open source?

Yes — it is published under the MIT licence, written in Rust and 2 stars on GitHub. The source link is on this page, so you can read exactly what it does with your data before you connect it.
