Get package details, versions, download counts, authors, licenses, and tags via the public NuGet API. - **URL**: https://apify.com/klondikeking/nuget-package-scraper.md - **Developed by:** [Pierrick McD0nald](https://apify.com/klondikeking) (community) - **Categories:** Developer tools, Business - **Stats:** 2 total users, 1 monthly users, 100.0% runs succeeded, NaN bookmarks - **User rating**: No ratings yet ## Pricing Pay per usage This Actor is paid per platform usage. The Actor is free to use, and you only pay for the Apify platform usage, which gets cheaper the higher subscription plan you have.

Actors are a software tools running on the Apify platform, for all kinds of web data extraction and automation use cases. In Batch mode, an Actor accepts a well-defined JSON input, performs an action which can take anything from a few seconds to a few hours, and optionally produces a well-defined JSON output, datasets with results, or files in key-value store. In Standby mode, an Actor provides a web server which can be used as a website, API, or an MCP server. Actors are written with capital "A". ## How to integrate an Actor? If asked about integration, you help developers integrate Actors into their projects. You adapt to their stack and deliver integrations that are safe, well-documented, and production-ready. The best way to integrate Actors is as follows. In JavaScript/TypeScript projects, use official [JavaScript/TypeScript client](https://docs.apify.com/api/client/js.md): ```bash npm install apify-client ``` In Python projects, use official [Python client library](https://docs.apify.com/api/client/python.md): ```bash pip install apify-client ``` In shell scripts, use [Apify CLI](https://docs.apify.com/cli/docs.md): ````bash # MacOS / Linux curl -fsSL https://apify.com/install-cli.sh | bash # Windows irm https://apify.com/install-cli.ps1 | iex ```bash In AI frameworks, you might use the [Apify MCP server](https://docs.apify.com/platform/integrations/mcp.md). If your project is in a different language, use the [REST API](https://docs.apify.com/api/v2.md). For usage examples, see the [API](#api) section below. For more details, see Apify documentation as [Markdown index](https://docs.apify.com/llms.txt) and [Markdown full-text](https://docs.apify.com/llms-full.txt). # README ## NuGet Package Scraper — .NET Package & Library Extractor Extract .NET package metadata from NuGet Gallery via its public search API. Search by keyword or package ID to retrieve package details, versions, download counts, authors, licenses, tags, and verification status. Ideal for dependency research, security auditing, and .NET ecosystem analysis. ### Use Cases - **Dependency Research** — Find NuGet packages by name or keyword for project references and `PackageReference` configuration - **Security Auditing** — Extract version counts, verification status, and license URLs to identify risky or outdated dependencies - **Ecosystem Analysis** — Batch-search NuGet to map .NET library trends, popular packages, and download metrics - **License Compliance** — Gather package metadata and license URLs for open-source compliance reporting ### Input | Field | Type | Required | Description | |-------|------|----------|-------------| | `searchQueries` | Array | No | Search terms to query NuGet Gallery (e.g., `["Newtonsoft.Json", "Serilog"]`). Each term returns up to `maxResults` packages. | | `packageId` | String | No | Exact NuGet package ID to fetch (e.g., `Newtonsoft.Json`). | | `includeAllVersions` | Boolean | No | If `true`, fetches all published versions for each package. Default: `false`. | | `includePrerelease` | Boolean | No | If `true`, includes prerelease versions in search results. Default: `false`. | | `maxResults` | Integer | No | Maximum packages per query (1–1000). Default: `100`. | | `proxyConfiguration` | Object | No | Proxy settings for requests. Built-in proxy support included by default. | ### Output The Actor outputs a dataset with the following fields: ```json { "packageId": "Newtonsoft.Json", "version": "13.0.5-beta1", "latestVersion": "13.0.5-beta1", "title": "Json.NET", "description": "Json.NET is a popular high-performance JSON framework for .NET", "summary": "", "authors": ["James Newton-King"], "owners": ["dotnetfoundation", "jamesnk", "newtonsoft"], "totalDownloads": 8212914731, "verified": true, "licenseUrl": "https://www.nuget.org/packages/Newtonsoft.Json/13.0.5-beta1/license", "projectUrl": "https://www.newtonsoft.com/json", "iconUrl": "https://api.nuget.org/v3-flatcontainer/newtonsoft.json/13.0.5-beta1/icon", "tags": ["json"], "packageTypes": ["Dependency"], "versionCount": 54, "searchQuery": "Newtonsoft.Json" } ```` When `includeAllVersions` is enabled, each version becomes a separate row with its own `version` field. ### Pricing Pay per event: **$0.002 per package scraped**. Charging is applied after each batch of results. The Actor respects spending limits and stops gracefully when the limit is reached. ### Limitations - NuGet Gallery API has no documented rate limits, but excessive volume may trigger throttling. Use reasonable `maxResults` values. - The API returns only packages published to NuGet Gallery. Private feeds or other hosts (MyGet, Azure Artifacts) are not covered. - `includeAllVersions` returns versions from the search index, but individual version publish dates are not available in the search endpoint. ### FAQ **Q: Do I need a NuGet API key?** A: No. This Actor uses the public NuGet search endpoint which requires no authentication. **Q: Can I search by partial package name?** A: Yes. Use `searchQueries` with partial names. The Actor queries NuGet's search index which supports partial matching. **Q: What is the difference between `latestVersion` and `version`?** A: `latestVersion` is the most recent version known for the package. `version` is the specific version of that row. When `includeAllVersions` is disabled, they are identical. **Q: How do I find all packages by an author?** A: Use `searchQueries` with the author or organization name. NuGet search supports author-based queries. ### Changelog - **v1.0.0** — Initial release. Search by query or package ID. Optional full version history. # Actor input Schema ## `searchQueries` (type: `array`): List of search terms to query NuGet Gallery (e.g., Newtonsoft, EntityFramework, Serilog) ## `packageId` (type: `string`): Exact NuGet package ID to fetch (optional, e.g., Newtonsoft.Json) ## `includeAllVersions` (type: `boolean`): If true, fetches all published versions for each package.
