What you get per package

registry, name, version, description, author, homepage, repository (decoded to a browseable https URL), license, keywords, monthlyDownloads (npm), and url (the human-facing registry page).

Nullable fields. Registries don't always populate every field, so the following can be null: description, author, homepage, repository, license (and keywords may be an empty array). monthlyDownloads is null when includeDownloads is off, for PyPI packages (no public download endpoint), or if the npm downloads API call fails for a specific package — in which case a warning is logged so you know why.

Input

Field	Notes
`registry`	`npm` or `pypi`. Default `npm`.
`searchQuery`	Keyword search — npm only (PyPI has no clean public search API).
`packageNames`	Array of exact names — works for both registries (e.g. `["requests","fastapi"]`, or npm scoped `["@types/node"]`).
`includeDownloads`	Fetch last-month download counts for npm packages. On by default. npm only.
`maxItems`	Cap on npm search results. Default 50.

You must provide either a searchQuery (npm) or one or more packageNames.

Registries

npm — keyword search via the registry search API, package detail via registry.npmjs.org/{pkg}, and monthly downloads via api.npmjs.org.
PyPI — exact-name lookup via pypi.org/pypi/{pkg}/json. PyPI has no clean public search API, so a searchQuery with registry=pypi returns a single diagnostic row telling you to use packageNames instead.

Output

One dataset row per package, deduped by registry + name. Packages that can't be found, and empty searches, return a single diagnostic row (ok:false) and are not charged.

Pricing

Pay-per-result: you are charged once per successfully returned package row. Diagnostic rows (ok:false) — bad input, not-found packages, empty searches, network/registry errors — are never charged.

Proxy

These are public, no-auth registries with no anti-bot, so no proxy is needed — leave proxy off (the default). Only enable a proxy if you hit IP-based rate limits on very large runs.

Troubleshooting

Empty/bad-input run returns a BAD_INPUT diagnostic row: provide a searchQuery (npm) or one or more packageNames.
monthlyDownloads is null for some npm packages: the downloads API occasionally rate-limits or has no data for a package; the run logs a warning and continues with null for that field.
PyPI search isn't supported (PyPI has no clean public search API); use exact packageNames with registry=pypi.

Examples

Search npm:

{ "registry": "npm", "searchQuery": "react state management", "maxItems": 25, "includeDownloads": true }

Look up Python packages:

{ "registry": "pypi", "packageNames": ["requests", "fastapi"] }
