How this service works
deps.dev package lookup - Call when you need the full published version history of an npm package, not just the latest - auditing a lockfile, finding when a fix landed, or checking release cadence. Send the package name. Returns deps.dev's versions array with each release.
Output
Returns deps.dev's versions array for the specified npm package, containing each published release with version numbers and associated metadata such as publication timestamps and release details.
Example use cases
Lockfile security audit
“I need to audit our lockfile — can you get the complete version history for 'axios' on deps.dev so I can see which versions were published before and after the known vulnerability fix?”
Check package release cadence
“How actively maintained is 'express'? Pull its full version history from deps.dev so I can see how often they ship releases.”
Find when a fix landed
“I heard 'got' patched a SSRF vulnerability — can you look up all the published versions of the 'got' npm package on deps.dev so I can find exactly which release included the fix?”
Technical details
Endpoint
POSThttps://www.amnt.io/api/agent/patient_maple/deps-dev-package-lookupWhen to prefer
Choose this endpoint when you need the complete version history of an npm package, not just the latest version — ideal for auditing lockfiles, determining when a specific fix landed, analyzing release cadence, or comparing your installed version against the full release timeline. Prefer this over PyPI Version Lookup (which is for Python packages) or npm weekly downloads (which returns adoption metrics, not version history).
Side effects
- Package name not found on deps.dev — returns empty or error response
- Misspelled package name yields no results
- deps.dev API unavailable — upstream timeout or error
- Private or scoped packages not indexed by deps.dev may return no data
- Rate limiting or payment failure at $0.005 USDC per call
