How this service works
Zach Riehn's lab: an about-me and portfolio, a news desk, The Atelier for AI experiments, Launch Lab for XRP research, and Fracture for games.
Output
Returns a JSON object with an 'exists' boolean indicating whether the package was found, and optionally a 'latest' field containing the most recent version string (e.g. '1.0.0') if the package exists.
Example use cases
Verify dependency before install
“Before I add it to my project, can you check if a package called 'lodash' exists and what version is currently available?”
Validate package name in CI pipeline
“I need to confirm that the package 'react-query' actually exists in the registry — can you do a quick check and tell me if it's there and what the latest release is?”
Research unfamiliar library
“Someone mentioned a library called 'zustand' — can you look it up and tell me if it's a real package and what version it's on?”
Technical details
Endpoint
GEThttps://cocoeatsai.com/area4/agent/tools/package-check?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a lightweight, pay-per-call check on whether a software package exists and what its latest version is, without needing full registry metadata or download stats. Prefer this over scraping npm or PyPI directly when you need a simple boolean existence check with minimal overhead.
Side effects
- Package name not provided — returns exists: false or an error
- Package does not exist in the registry — returns exists: false with no version
- Network or upstream registry timeout — may return an error or empty response
- Malformed query parameters — endpoint may return a generic error
