## Pricing

from $0.55 / 1,000 package scrapeds

This Actor is paid per event. You are not charged for the Apify platform usage, but only a fixed price for specific events.
Since this Actor supports Apify Store discounts, the price gets lower the higher subscription plan you have.

## What's an Apify Actor?

Actors are web data automations that power AI and operations. They run on the Apify platform to scrape websites, process data, connect APIs, and automate workflows.
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.

- **AI agents and MCP clients** — the [Apify MCP server](https://docs.apify.com/integrations/mcp.md) at `https://mcp.apify.com` (remote, streamable HTTP, OAuth on first use).
- **Agentic workflows and local Actor development** — [Agent Skills](https://apify.com/.well-known/agent-skills/index.json) with the [Apify CLI](https://docs.apify.com/cli/docs.md): `npm install -g apify-cli`, then `apify login`.
- **JavaScript/TypeScript projects** — the official [JS/TS client](https://docs.apify.com/api/client/js/docs.md): `npm install apify-client`.
- **Python projects** — the official [Python client](https://docs.apify.com/api/client/python/docs.md): `pip install apify-client`.
- **Any other language** — the [REST API](https://docs.apify.com/api/v2.md).

For usage examples, see the [API](#api) section below.

# README

## NuGet Scraper - .NET Packages & Downloads

Search **NuGet** or look up **.NET packages** by id and get clean rows: **total downloads**, **latest
version**, **authors**, **owners**, **tags**, **verified flag**, **package types**, **version count** and
**project / license / icon URLs**. Built on the official NuGet search API - no API key, no browser, no proxy.
Run one search or import a file of package ids.

### What you get per package

| Field | Meaning |
|---|---|
| `id` / `version` / `title` | Package id, latest version and display title |
| `description` / `summary` | Full description and (legacy) summary |
| `totalDownloads` / `verified` | Total downloads and the verified-owner flag |
| `authors` / `owners` | Author and owner lists |
| `tags` / `packageTypes` | Search tags and package types (Dependency, Template, ...) |
| `projectUrl` / `licenseUrl` / `iconUrl` | Project, license and icon URLs |
| `versionCount` / `registrationUrl` / `packageUrl` | Number of versions, registration index and the nuget.org page |

### Input

```json
{ "searchQueries": ["logging", "json"], "maxItemsPerQuery": 50 }
```

- **Search terms** - one per line (e.g. `json`, `logging`, `orm`).
- **Package ids** - fetch exact packages (e.g. `Newtonsoft.Json`, `Serilog`).
- **Include prerelease** - set `prerelease` to include beta / rc packages.
- **Import from a file** - paste a list, or link a public `.txt`/`.csv`, a Google Sheet/Drive link, or an
  Apify key-value-store record.
- **Output fields** - trim every record to exactly the columns you need.

Leave everything empty and the run returns a small free sample so you can see the shape first.

### Reliability

Reads the **official NuGet SearchQueryService** with automatic failover between its two hosts - no key, no
proxy, no anti-bot. A search that returns nothing, an unknown package id, or an import that cannot be read
bills **$0** and says why.

### Honest limits

- **`summary` is a legacy field** - modern packages fill `description` and leave `summary` empty; an honest
  null/empty when the publisher set none (probed 2026-08-15). `description` is populated on essentially every package.
- **`totalDownloads`** is NuGet's own aggregate across all versions of the package.
- **Results are relevance-ranked by NuGet** - the search service orders by its own relevance, not a
  caller-chosen sort.

### Pricing

**$0.001 per package** on the FREE tier (tiered pricing lowers it with volume). Only packages actually saved
are billed; empty searches, unknown ids and unreadable imports cost nothing.

### Output views

- **Packages** - id, version, description, total downloads, verified flag and project URL.

### Use with AI assistants (MCP)

Available through the [Apify MCP server](https://docs.apify.com/platform/integrations/mcp) - an agent can find
the most-downloaded .NET library for a task, check whether a package is owner-verified, or enrich a list of
package ids with versions and project links in one call.

### Agent-ready: autonomous payments (x402 & Skyfire)

This actor is **agent-ready** - AI agents can discover it, run it, and **pay for it autonomously**, with no Apify account and no human in the loop. It uses [pay-per-event](https://docs.apify.com/platform/actors/publishing/monetize/pay-per-event) pricing and [limited permissions](https://docs.apify.com/platform/actors/development/permissions), so it qualifies for Apify's agentic-payment standards:

- **[x402](https://docs.apify.com/platform/integrations/x402)** - an open, HTTP-native payment protocol. Agents pay per run in USDC on the Base network directly through the [Apify MCP server](https://docs.apify.com/platform/integrations/mcp) - no account, no API key.
- **[Skyfire](https://docs.apify.com/platform/integrations/skyfire)** - agent-to-service payments for fully autonomous AI-agent workflows.

Building an AI agent, MCP tool, or autonomous data pipeline? This scraper is ready to plug in and pay as it goes.

# Actor input Schema

## `searchQueries` (type: `array`):

Terms to search NuGet for, one per line - e.g. <code>json</code>, <code>logging</code>, <code>orm</code>. <b>Leave empty and the run returns a small free sample.</b>

## `packageIds` (type: `array`):

Specific package ids to fetch exactly, one per line - e.g. <code>Newtonsoft.Json</code>, <code>Serilog</code>.

## `prerelease` (type: `boolean`):

Include prerelease (beta/rc) packages in the results.

## `searchQueriesFromFile` (type: `string`):

Bulk-load search terms. Either <b>paste the whole list</b> (one per line), or give <b>a single link</b> to a public <code>.txt</code>/<code>.csv</code>, a Google Sheet/Drive link, or an Apify key-value-store record. A file that cannot be read says so and charges nothing.

## `maxItemsPerQuery` (type: `integer`):

How many packages to collect for each search term.

## `maxItems` (type: `integer`):

Overall cap across all searches and ids. You are only charged for packages actually saved.

## `outputFields` (type: `array`):

Pick the fields you want and every record is trimmed to exactly those - handy for lean CSV/Sheets exports.

## Actor input object example

```json
{
  "searchQueries": [
    "json"
  ],
  "prerelease": false,
  "maxItemsPerQuery": 50,
  "maxItems": 1000
}
```

# Actor output Schema

## `results` (type: `string`):

Each scraped record - a NuGet package with downloads, version, authors and tags - as a JSON item in the default dataset.

# API

You can run this Actor programmatically using our API. Below are code examples in JavaScript, Python, and CLI, as well as the OpenAPI specification and MCP server setup.

});

// Prepare Actor input
const input = {
    "searchQueries": [
        "json"
    ],
    "searchQueriesFromFile": ""

// Run the Actor and wait for it to finish
const run = await client.actor("scrapesage/nuget-scraper").call(input);

// Fetch and print Actor results from the run's dataset (if any)
console.log('Results from dataset');
console.log(`💾 Check your data here: https://console.apify.com/storage/datasets/${run.defaultDatasetId}`);
const { items } = await client.dataset(run.defaultDatasetId).listItems();
items.forEach((item) => {
    console.dir(item);
});

## CLI example

```bash
echo '{
  "searchQueries": [
    "json"
  ],
  "searchQueriesFromFile": ""
}' |
apify call scrapesage/nuget-scraper --silent --output-dataset

```

## MCP server setup

```json
{
    "mcpServers": {
        "apify": {
            "type": "http",
            "url": "https://mcp.apify.com/?tools=fetch-actor-details,scrapesage/nuget-scraper"
        }
    }
}

```

The hosted server signs you in with OAuth on first connect, so no API token belongs in this config. Clients without OAuth support can send an `Authorization: Bearer <APIFY_API_TOKEN>` header instead, using a token from API & Integrations in Apify Console (https://console.apify.com/settings/integrations).
