Input

{
  "packages": ["react", "@babel/core"],
  "daysBack": 30,
  "maxResultsPerPackage": 10
}

Field	Type	Description
`packages`	array of strings	npm package names, including scoped packages (e.g. `"@babel/core"`). One lookup is billed per package.
`daysBack`	number	Only return versions published within this many days of today. Default `30`, max `365`.
`maxResultsPerPackage`	number	Max published versions to return per package, most recent first. Default `10`, max `50`.

Output

One record per published version:

{
  "packageName": "react",
  "version": "19.2.8",
  "publishedAt": "2026-07-21T15:41:28.716Z",
  "isLatest": true,
  "versionDeprecationMessage": null,
  "packageDeprecationMessage": null,
  "tarballUrl": "https://registry.npmjs.org/react/-/react-19.2.8.tgz"
}

A package with no versions published in the requested window returns no items but is still billed once for the lookup.

How it works

Direct calls to the official npm registry API — the same registry npm install talks to. No proxy, no key, no scraping.

Pricing note

Billed per package checked, not per version returned — one charge per package whether it has 0 or 50 matching versions.
