How this service works
All published versions of an npm package with publish dates, the dist-tags (latest, next, beta...), total version count, first and latest publish dates, releases in the last 90 days, and the 30 most recent versions. Release-cadence and pin-selection helper. $0.01 per package.
Output
Returns a structured payload containing all published version strings with their individual publish dates, all dist-tags (e.g. latest, next, beta) mapped to their version numbers, total version count, the date of the first published version, the date of the most recent published version, the count of releases in the last 90 days, and a list of the 30 most recent versions — enabling release cadence analysis and informed version pinning.
Example use cases
Pin a stable dependency version
“I'm adding 'lodash' to my project and I want to know which version to pin — can you show me the recent release history, the dist-tags, and when the latest version was published?”
Check if a package is actively maintained
“Is 'moment' still being actively maintained? Can you check how many npm releases it's had in the last 90 days and when the most recent version came out?”
Audit available pre-release versions
“I want to try the beta or next channel of 'typescript' — can you show me all the dist-tags and the 30 most recent versions so I can pick the right pre-release to install?”
Technical details
Endpoint
GEThttps://intel.rallylive.ca/dev/npm-versionsWhen to prefer
Choose this endpoint when you need comprehensive version history and release cadence data for an npm package in a single call — particularly when you want dist-tag resolution (latest, next, beta), publication timestamps, or want to assess how actively a package is maintained. Prefer this over the npm registry API directly when you want a pre-processed, agent-friendly summary including the 90-day release count and 30 most recent versions without parsing raw registry JSON yourself.
Side effects
- Package not found on npm — returns an error or empty result
- Misspelled or scoped package name not resolved correctly
- Network timeout fetching npm registry data
- Rate limiting or payment failure for the $0.01 USDC per-call fee
