What it does. Looks up npm and PyPI packages through the official public registry JSON APIs and returns one row per package: latest version, license, description, keywords, homepage, repository and issue links, version count, dependency count, publish dates and (npm) weekly/monthly downloads.
Input
packages: names, one per line; prefixnpm:orpypi:per name, or setecosystem(npm, pypi, both). Scoped npm names (@types/node) work.includeDownloads(default on): npm download counts from api.npmjs.org.maxItems: up to 5,000.
Output fields
ecosystem, name, latestVersion, description, license, keywords, homepage, repositoryUrl, bugsUrl, versionsCount, dependenciesCount, requiresPython, nodeEngine, deprecated, createdAt, latestPublishedAt, modifiedAt, downloadsLastWeek, downloadsLastMonth, packageUrl
Free status rows (not charged): no-results (package not found), invalid-input, api-error, free-plan-limit, charge-limit-reached.
PyPI's JSON API publishes no download counts, so download fields are empty for PyPI rows.
Example (the build's prefill): {"packages":["npm:lodash","pypi:requests"]}
Data source and compliance
- Data from the npm public registry (registry.npmjs.org, api.npmjs.org) and the Python Package Index JSON API (pypi.org). Official JSON APIs only; no website pages are scraped.
- Privacy: author and maintainer names and email addresses are dropped entirely. Only a fixed list of package fields is returned.
- Independent Lepi Data tool, not affiliated with or endorsed by npm, Inc., GitHub, the Python Software Foundation or PyPI. No logos are used. npm is a trademark of npm, Inc.; "PyPI" and "Python" are trademarks of the PSF.
- About one request per second, with back-off on errors.
- Free-plan accounts get up to 100 results per run.
Pricing. Pay per package row, flat on every plan, no start fee. Free status rows are never charged.
