Search by keyword, filter by package type, get detailed metadata including versions, authors, download counts, and license info. - **URL**: https://apify.com/crawlerbros/nuget-scraper.md - **Developed by:** [Crawler Bros](https://apify.com/crawlerbros) (community) - **Categories:** Developer tools, Automation - **Stats:** 2 total users, 1 monthly users, 100.0% runs succeeded, 4 bookmarks - **User rating**: 5.00 out of 5 stars ## 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 Scraper Scrape **NuGet.org** — the official .NET package registry with 600K+ packages. Extract package metadata including versions, authors, download statistics, license information, and more — all without authentication or API keys. ### What does NuGet Scraper do? NuGet Scraper lets you: - **Search** for packages by keyword with optional filters (package type, pre-release, sort order) - **Look up** any specific package by its exact ID - **Browse** all packages published by a specific author or organization - **Retrieve** aggregate download statistics for the NuGet ecosystem All data is sourced from the official [NuGet V3 API](https://docs.microsoft.com/en-us/nuget/api/overview), which is free, public, and imposes no rate limits for reasonable use. ### Input | Field | Type | Required | Description | |-------|------|----------|-------------| | `mode` | Select | ✅ | Operation mode: `search`, `byPackageId`, `byAuthor`, or `statistics` | | `query` | Text | mode=search | Search keyword (e.g. `Newtonsoft.Json`, `logging`, `Microsoft`) | | `packageId` | Text | mode=byPackageId | Exact package ID (e.g. `Serilog`) | | `author` | Text | mode=byAuthor | Author or organization name (e.g. `Microsoft`, `JetBrains`) | | `packageType` | Select | No | Filter by type: `Dependency`, `DotnetTool`, `DotnetCliTool`, `Template` | | `prerelease` | Boolean | No | Include pre-release packages (default: `false`) | | `sortBy` | Select | No | Sort: `relevance`, `totalDownloads`, `lastEdited`, `newlyCreated` | | `maxItems` | Integer | No | Max packages to return (1–1000, default: `50`) | #### Example inputs **Search for JSON packages:** ```json { "mode": "search", "query": "Newtonsoft.Json", "maxItems": 10 } ```` **Look up a specific package:** ```json { "mode": "byPackageId", "packageId": "AutoMapper" } ``` **Browse Microsoft packages:** ```json { "mode": "byAuthor", "author": "Microsoft", "maxItems": 50 } ``` **Get NuGet statistics:** ```json { "mode": "statistics" } ``` ### Output Each record in the dataset contains: | Field | Type | Description | |-------|------|-------------| | `id` | String | Package ID (e.g. `Newtonsoft.Json`) | | `version` | String | Latest version (e.g. `13.0.3`) | | `description` | String | Full package description | | `summary` | String | Short summary (if available) | | `authors` | Array | List of author names | | `tags` | Array | Package tags/keywords | | `totalDownloads` | Integer | Total all-time downloads | | `verified` | Boolean | Whether the package is verified by NuGet | | `projectUrl` | String | Project homepage URL | | `licenseUrl` | String | License URL | | `iconUrl` | String | Package icon URL | | `packageTypes` | Array | Package types (e.g. `["Dependency"]`) | | `publishedDate` | String | Publication date (ISO 8601) | | `nugetUrl` | String | Direct URL on NuGet.org | | `scrapedAt` | String | Timestamp when the record was scraped | #### Example output record ```json { "id": "Newtonsoft.Json", "version": "13.0.3", "description": "Json.NET is a popular high-performance JSON framework for .NET", "summary": "Popular JSON framework", "authors": ["James Newton-King"], "tags": ["json", "serialization", "linq"], "totalDownloads": 4500000000, "verified": true, "projectUrl": "https://www.newtonsoft.com/json", "licenseUrl": "https://licenses.nuget.org/MIT", "packageTypes": ["Dependency"], "nugetUrl": "https://www.nuget.org/packages/Newtonsoft.Json", "scrapedAt": "2026-05-25T12:00:00+00:00" } ``` ### Modes #### `search` — Search packages by keyword Search NuGet for packages matching a keyword. Supports filtering by package type (library, tool, template) and sorting by various criteria. #### `byPackageId` — Get a specific package Fetch full metadata for a single package by its exact NuGet ID. Includes published date from the registration API. #### `byAuthor` — Browse by author Search for all packages from a specific author or organization (e.g. `Microsoft`, `JetBrains`, `Autofac`). #### `statistics` — Download statistics Retrieve aggregate download statistics for the entire NuGet ecosystem. ### FAQ **Do I need an API key?** No. NuGet's V3 API is completely public and requires no authentication. **How many packages can I scrape?** Up to 1,000 per run with the `maxItems` parameter. For bulk scraping, run multiple times with different queries. **Can I get all versions of a package?** The scraper returns the latest stable version. For version history, use `byPackageId` mode which fetches registration data. **Are pre-release packages included?** Set `prerelease: true` to include alpha/beta packages in search results. **What package types are available?** - `Dependency` — Standard .NET library - `DotnetTool` — Global or local .NET tool - `DotnetCliTool` — Legacy .NET CLI tool - `Template` — Project/item template for `dotnet new` **Is proxy required?** No. NuGet.org's public API has no geo-restrictions and requires no proxy. # Actor input Schema ## `mode` (type: `string`): Operation mode: search packages, fetch a specific package by ID, browse by author, or get download statistics. ## `query` (type: `string`): Keyword or phrase to search for packages (mode=search). ## `packageId` (type: `string`): Exact NuGet package ID to look up (mode=byPackageId).
