## 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

## Crates.io Scraper – Rust Packages, Downloads & Repos

**Get clean crates.io data for any Rust package: total & recent downloads, latest version, description, keywords, categories, homepage, repository and docs. Search by query or fetch specific crates by name. As JSON, CSV or Excel. Free, no key, no proxy.**

### 💵 Pricing

**Pay per result — about $0.0004 per item ($0.40 / 1,000).** No subscription, no proxy needed. You only pay for the data you scrape, and new Apify accounts include free monthly credits so you can test it for **$0**.

### 🔎 What can it extract?

- Crate name, description, latest (max) version
- **Total downloads & recent downloads**
- Keywords and categories
- Homepage, repository and documentation links
- Created / updated timestamps
- Direct crate URL (`https://crates.io/crates/{name}`)

### 🚀 How do I use it?

1. Click **Try for free**.
2. Set the input (see example below).
3. Click **Start** and download results as JSON, CSV or Excel — or pull them via the API / schedule them.

### ⚙️ Input example

```json
{
  "mode": "search",
  "query": "web scraping",
  "sort": "downloads",
  "maxItems": 100
}
```

Fetch specific crates with full keywords + categories:

```json
{
  "mode": "crates",
  "crateNames": ["tokio", "serde"]
}
```

### 📦 Output example

```json
{
  "name": "tokio",
  "description": "An event-driven, non-blocking I/O platform for writing asynchronous I/O backed applications.",
  "downloads": 350000000,
  "recent_downloads": 42000000,
  "max_version": "1.38.0",
  "homepage": "https://tokio.rs",
  "repository": "https://github.com/tokio-rs/tokio",
  "documentation": "https://docs.rs/tokio",
  "keywords": ["io", "async", "non-blocking", "futures"],
  "categories": ["asynchronous", "network-programming"],
  "created_at": "2016-08-15T09:00:00.000000+00:00",
  "updated_at": "2024-06-01T09:00:00.000000+00:00",
  "url": "https://crates.io/crates/tokio",
  "scraped_at": "2026-07-01T12:00:00+00:00"
}
```

### 🎯 Use cases

- Rust dependency & supply-chain analysis
- Tracking package popularity and download trends
- Building developer-tooling and package datasets
- Discovering crates by keyword or category
- Competitive research on the Rust ecosystem

### 💰 How much will it cost?

You pay only the per-result price (no proxy cost):
100 → ~$0.04 · 1,000 → ~$0.40 · 10,000 → ~$4

# Actor input Schema

## `mode` (type: `string`):

How to fetch data: 'search' finds crates by a text query (sorted), 'crates' fetches full detail (incl. keywords + categories) for specific crate names.

## `query` (type: `string`):

Text to search crates.io for (mode=search), e.g. 'web scraping', 'async', 'http'.

## `crateNames` (type: `array`):

Exact crate names to fetch full detail for (mode=crates), e.g. tokio, serde. Batch is capped at 50 per run.

## `sort` (type: `string`):

Sort order for search results: total downloads, recent downloads, most recently updated, or relevance to the query.

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

Maximum number of crates to return (search mode). One crate = one dataset item.

## Actor input object example

```json
{
  "mode": "search",
  "query": "web scraping",
  "crateNames": [
    "tokio",
    "serde"
  ],
  "sort": "downloads",
  "maxItems": 100
}
```

const run = await client.actor("ninhothedev/crates-io-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();

## CLI example

```bash
echo '{
  "query": "web scraping",
  "crateNames": [
    "tokio",
    "serde"
  ],
  "maxItems": 100
}' |
apify call ninhothedev/crates-io-scraper --silent --output-dataset

```

## MCP server setup

```json
{
    "mcpServers": {
        "apify": {
            "type": "http",
            "url": "https://mcp.apify.com/?tools=fetch-actor-details,ninhothedev/crates-io-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).
