- [Human guide](https://firecrawl.dev/app/alexandria/npmjs-com)
- [OpenAPI spec](https://firecrawl.dev/alexandria/agents/providers/npmjs-com/openapi.json)

## Capabilities

- [Get download range](https://firecrawl.dev/alexandria/agents/providers/npmjs-com/packages/get_download_range): Daily download counts for one package over a period (`api.npmjs.org/downloads/range/{period}/{name}`): one row per day plus the period total.
- [Get downloads](https://firecrawl.dev/alexandria/agents/providers/npmjs-com/packages/get_downloads): Download counts for one or more packages over a period from npm's downloads API (`api.npmjs.org/downloads/point/{period}/{names}`). Unscoped names are fetched in one bulk request; scoped names (`@scope/name`) one request each, as the API requires. A package the API does not know is reported with null counts when several are asked, and as `not_found` when it is the only one.
- [Get package](https://firecrawl.dev/alexandria/agents/providers/npmjs-com/packages/get_package): One package's registry document (`registry.npmjs.org/{name}`): identity, description, license, homepage, repository and bug tracker, keywords, author and maintainers, every dist-tag, the latest version and its publish time, creation and last-modified times, the version count and how many versions are deprecated. Optionally every version with publish time, license and deprecation notice, and the README.
- [Get package version](https://firecrawl.dev/alexandria/agents/providers/npmjs-com/packages/get_package_version): One published version (or dist-tag) of a package from the registry (`registry.npmjs.org/{name}/{version}`): description, license, deprecation notice, entry points, engines, runtime/dev/peer/optional dependencies with their ranges, install-script flag, tarball URL with shasum, integrity, file count and unpacked size, publisher and git commit.
- [Get version downloads](https://firecrawl.dev/alexandria/agents/providers/npmjs-com/packages/get_version_downloads): Last-week download counts per published version of one package (`api.npmjs.org/versions/{name}/last-week`, the only period npm serves), sorted by downloads descending, with the total. An unknown package is `not_found` (checked against the registry, because the API answers an empty map for both unknown packages and packages with no downloads).
- [List dependents](https://firecrawl.dev/alexandria/agents/providers/npmjs-com/packages/list_dependents): Packages that depend on a package, most recently published first, from npmjs.com's dependents listing (`/browse/depended/{name}?offset=`): 36 per page with latest version, description, publisher, maintainers, dist-tags and publish time. `cursor` is the offset of the next page. An unknown package is `not_found` (checked against the registry, because the listing answers an empty page for both unknown packages and packages without dependents). Served from a public cache of up to 4 hours.
- [List owner packages](https://firecrawl.dev/alexandria/agents/providers/npmjs-com/packages/list_owner_packages): Packages maintained by a user (`npmjs.com/~{user}`) or owned by an organization (`npmjs.com/org/{org}`): the owner record (type, name, full name or GitHub handle, creation time), the total and one page of 25 packages with latest version, description, publisher, maintainers, dist-tags, publish, creation and update times and npm's high-impact flag. `page` is 0-based; the site's pagination reports whether a next page exists. Served from a public cache of up to 4 hours.
- [Search packages](https://firecrawl.dev/alexandria/agents/providers/npmjs-com/packages/search_packages): Full-text package search on the npm registry (`registry.npmjs.org/-/v1/search`): every hit with its latest version, description, keywords, license, publisher and maintainers, publish date, links, weekly and monthly downloads, dependents count and npm's quality/popularity/maintenance score. Supports the registry's query qualifiers (`keywords:cli`, `author:sindresorhus`, `scope:types`, `not:deprecated`, `is:unstable`). Pages of `size` hits; `cursor` is the offset of the next page.
- [Suggest packages](https://firecrawl.dev/alexandria/agents/providers/npmjs-com/packages/suggest_packages): Typeahead suggestions from npmjs.com (`/search/suggestions?q=`): the handful of packages the site proposes for a prefix, each with latest version, description, publisher, publish date, weekly/monthly downloads and dependents count.

## 1. Choose this provider when

npm, the JavaScript package registry: full-text and typeahead package search, package documents with dist-tags and version history, per-version dependencies and tarballs, download counts (totals, daily series, per version), dependents and packages by user or organization.

## 2. Minimal request

Call `POST https://api.firecrawl.dev/v2/scrape` with `{ alexandria: { provider, capability, options } }`. For a batch, send `{ alexandria: [...] }` with up to 10 calls.

```json
{
  "provider": "npmjs-com",
  "capability": "packages/get_download_range",
  "options": {
    "package": "express",
    "period": "last-week"
  }
}
```

## 3. Add provider options

Use only the options needed for the task:

- `package` (string, required): Package name as on npm, e.g. `express` or `@types/node` (scoped names unencoded). Pattern: ^(@[A-Za-z0-9~-][A-Za-z0-9._~-]*/)?[A-Za-z0-9~-][A-Za-z0-9._~-]*$. Example: `<package>`
- `period` (string): `last-day`, `last-week`, `last-month`, `last-year`, a single `YYYY-MM-DD` or a `YYYY-MM-DD:YYYY-MM-DD` range (npm caps ranges at 18 months). Counts lag the current day by 1-3 days. Pattern: ^(last-day|last-week|last-month|last-year|[0-9]{4}-[0-9]{2}-[0-9]{2}(:[0-9]{4}-[0-9]{2}-[0-9]{2})?)$. Example: `last-month`

### Get version downloads

- Capability: `packages/get_version_downloads`
- Description: Last-week download counts per published version of one package (`api.npmjs.org/versions/{name}/last-week`, the only period npm serves), sorted by downloads descending, with the total. An unknown package is `not_found` (checked against the registry, because the API answers an empty map for both unknown packages and packages with no downloads).
- Instructions: See which versions of a package are actually installed this week (major-version adoption, whether a deprecated line is still in use).
- Cost: 5 credits per call
- Capability file: [Get version downloads](https://firecrawl.dev/alexandria/agents/providers/npmjs-com/packages/get_version_downloads)

Accepted options:
- `package` (string, required): Package name as on npm, e.g. `express` or `@types/node` (scoped names unencoded). Pattern: ^(@[A-Za-z0-9~-][A-Za-z0-9._~-]*/)?[A-Za-z0-9~-][A-Za-z0-9._~-]*$. Example: `<package>`

### List dependents

- Capability: `packages/list_dependents`
- Description: Packages that depend on a package, most recently published first, from npmjs.com's dependents listing (`/browse/depended/{name}?offset=`): 36 per page with latest version, description, publisher, maintainers, dist-tags and publish time. `cursor` is the offset of the next page. An unknown package is `not_found` (checked against the registry, because the listing answers an empty page for both unknown packages and packages without dependents). Served from a public cache of up to 4 hours.
- Instructions: Find who uses a package (recent adopters, plugins, wrappers); the total dependents count is in `search_packages` results.
- Cost: 5 credits per call
- Capability file: [List dependents](https://firecrawl.dev/alexandria/agents/providers/npmjs-com/packages/list_dependents)

Accepted options:
- `cursor` (string): `next_cursor` from a previous page (offset in items). Pattern: ^[0-9]+$. Example: `next_cursor`
- `package` (string, required): Package name as on npm, e.g. `express` or `@types/node` (scoped names unencoded). Pattern: ^(@[A-Za-z0-9~-][A-Za-z0-9._~-]*/)?[A-Za-z0-9~-][A-Za-z0-9._~-]*$. Example: `<package>`

### List owner packages

- Capability: `packages/list_owner_packages`
- Description: Packages maintained by a user (`npmjs.com/~{user}`) or owned by an organization (`npmjs.com/org/{org}`): the owner record (type, name, full name or GitHub handle, creation time), the total and one page of 25 packages with latest version, description, publisher, maintainers, dist-tags, publish, creation and update times and npm's high-impact flag. `page` is 0-based; the site's pagination reports whether a next page exists. Served from a public cache of up to 4 hours.
- Instructions: List everything a maintainer or an organization publishes; provide exactly one of `user` or `org`.
- Cost: 5 credits per call
- Capability file: [List owner packages](https://firecrawl.dev/alexandria/agents/providers/npmjs-com/packages/list_owner_packages)

Accepted options:
- `org` (string): npm organization (scope without `@`), as in `https://www.npmjs.com/org/{org}`. Pattern: ^[A-Za-z0-9][A-Za-z0-9._-]*$. Example: `@`
- `page` (number): 0-based page of 25 packages. Example: `0`
- `user` (string): npm username, as in `https://www.npmjs.com/~{user}`. Pattern: ^[A-Za-z0-9][A-Za-z0-9._-]*$. Example: `https://www.npmjs.com/~{user}`

### Search packages

- Capability: `packages/search_packages`
- Description: Full-text package search on the npm registry (`registry.npmjs.org/-/v1/search`): every hit with its latest version, description, keywords, license, publisher and maintainers, publish date, links, weekly and monthly downloads, dependents count and npm's quality/popularity/maintenance score. Supports the registry's query qualifiers (`keywords:cli`, `author:sindresorhus`, `scope:types`, `not:deprecated`, `is:unstable`). Pages of `size` hits; `cursor` is the offset of the next page.
- Instructions: Find npm packages by words, keyword, author or scope before looking one up by name; the registry returns up to 250 hits per page and reports the total.
- Cost: 5 credits per call
- Capability file: [Search packages](https://firecrawl.dev/alexandria/agents/providers/npmjs-com/packages/search_packages)

Accepted options:
- `cursor` (string): `next_cursor` from a previous page (the registry `from` offset). Pattern: ^[0-9]+$. Example: `next_cursor`
- `query` (string, required): Search text; qualifiers such as `keywords:cli author:sindresorhus` are passed through unchanged. Example: `keywords:cli author:sindresorhus`
- `size` (number): Hits per page (registry maximum 250). Example: `20`
