    Export the results

    Download as JSON, CSV or Excel, or pipe straight into your app, Google Sheets, or an AI agent.

Inputs

FieldWhat it doesType
registryWhich package registry to use. npm supports both keyword search and exact-name lookup; PyPI supports exact-name lookup only (it has no clean public search API).string
searchQueryKeywords to search the npm registry for (e.g. "react state management"). npm only — ignored for PyPI. Leave empty if you are looking up exact package names instead.string
packageNamesExact package names to look up directly. Works for BOTH registries. For PyPI this is the only supported mode (e.g. ["requests", "fastapi"]). For npm, scoped names like "@types/node" are supported.array
includeDownloadsFetch last-month download counts for each npm package via the npm downloads API. npm only — PyPI does not expose a public download-count endpoint. Adds one request per package. Note: monthlyDownloads is null when this is off, for PyPI packages, or if the downloads API call fails for a given package (a warning is logged in that case).boolean
maxItemsMaximum number of packages to return from an npm search query. Only applies to npm search; ignored for exact-name lookups.integer
notionConnectorOptional. Write each package as a page into your Notion when the run finishes. Authorize a Notion connector once in Settings → API & Integrations → MCP connectors, then pick it here. Leave empty to skip (default) — results are always saved to the dataset regardless.string
notionParentIdOptional. The Notion data source ID of the database to write into (only used if a Notion connector is set). Leave empty to create the pages privately in your workspace instead.string

What you get

A structured dataset — each result includes fields like:

Export every run as JSON, CSV or Excel, or send it to your app, a database, Google Sheets, or an AI agent.
