## What's an Apify Actor?

An Actor is a serverless cloud program that runs on the Apify platform. It has two run modes.
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.

Apify vocabulary and the platform model are defined once, in the agent quickstart at https://apify.com/agents.md.

## 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.

Do not guess an integration path. Every one of them is in the agent quickstart at https://apify.com/agents.md: the Apify MCP server, Agent Skills with the Apify CLI, the JavaScript and Python clients, the REST API, and the account-free path for an agent with no human to sign in. It also carries the rule on stating cost before the first paid run.

For examples already wired to this Actor's own input schema, see the [API](#api) section below.

Each client library has reference documentation the quickstart does not restate: [JavaScript/TypeScript](https://docs.apify.com/api/client/js/docs.md) (`npm install apify-client`) and [Python](https://docs.apify.com/api/client/python/docs.md) (`pip install apify-client`).

# README

Scrape **crates.io** — the Rust package registry with 340,000+ crates — through the **official API** over plain HTTP. No browser, no proxies, no API key.

### What you get

**Crate rows** — name, description, total + recent downloads, max/newest version, license, homepage, repository, documentation links, keywords, categories, creation & update dates, direct crates.io URL.

**Version rows** — version history per crate: version number, downloads, publish date, yanked flag, license.

### Key features

- **Search 340k+ crates** by keyword, category slug, or keyword-tag
- **5 sort orders**: most downloaded, trending downloads, recently updated, newest, alphabetical
- **Version history** with yanked-release detection — spot pulled releases instantly
- **Polite by design**: rate-limited requests, clean error rows, never silently empty
- **Empty input?** Returns a setup-guide row so automated checks never see an empty dataset

### Input

Type keywords into `searchQuery` (or leave empty to browse everything), pick a sort order, run.

### Pick your mode

| You need | Fill in | You pay for |
|---|---|---|
| Crates only | Search / crate names | `crate` $0.001 each |
| Versions too | Tick include versions | `version` $0.0005 each |

Unfilled inputs cost nothing — first 20 items per run are free anyway.

### Pricing

- **$0.001 per crate** ($1.00 / 1,000 crates)
- **$0.0005 per version** ($0.50 / 1,000 versions)
- First **20 items of every run are free** (crates + versions combined)
- Actor start: **$0.00005**
- Setup-guide and error rows are never charged

### Typical uses

- **Rust ecosystem research**: most-downloaded crates by category, trending packages
- **Dependency auditing**: version history, yanked releases, license inventory across your supply chain
- **Package datasets** for analysis, dashboards, and ML

# Actor input Schema

## `category` (type: `string`):

Filter by crates.io category slug, e.g. "command-line-utilities". Leave empty for all.

## `includeVersions` (type: `boolean`):

Fetch version history (version number, downloads, publish date, yanked flag) for each crate.

## `keyword` (type: `string`):

Filter by keyword tag, e.g. "async". Leave empty for all.

## `maxCrates` (type: `integer`):

Maximum crates to collect (API paginates automatically, 100 per page).

## `maxVersionsPerCrate` (type: `integer`):

How many recent versions to fetch per crate.

## `searchQuery` (type: `string`):

Search keywords, e.g. "web framework". Leave empty to browse all crates by sort order.

## `sortBy` (type: `string`):

How to order the crates.

## Actor input object example

```json
{
  "category": "",
  "includeVersions": true,
  "keyword": "",
  "maxCrates": 50,
  "maxVersionsPerCrate": 5,
  "searchQuery": "web framework",
  "sortBy": "downloads"
}
```

# 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.

## JavaScript example

```javascript
import { ApifyClient } from 'apify-client';

// Initialize the ApifyClient with your Apify API token
// Replace the '<YOUR_API_TOKEN>' with your token
const client = new ApifyClient({
    token: '<YOUR_API_TOKEN>',
});

// Prepare Actor input
const input = {
    "category": "",
    "includeVersions": true,
    "keyword": "",
    "maxCrates": 50,
    "maxVersionsPerCrate": 5,
    "searchQuery": "web framework",
    "sortBy": "downloads"
};

// Run the Actor and wait for it to finish
const run = await client.actor("celebrated-quadraphonic/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();
items.forEach((item) => {
    console.dir(item);
});

## Python example

```python
from apify_client import ApifyClient

# Initialize the ApifyClient with your Apify API token
# Replace '<YOUR_API_TOKEN>' with your token.
client = ApifyClient("<YOUR_API_TOKEN>")

# Prepare the Actor input
run_input = {
    "category": "",
    "includeVersions": True,
    "keyword": "",
    "maxCrates": 50,
    "maxVersionsPerCrate": 5,
    "searchQuery": "web framework",
    "sortBy": "downloads",
}

# Run the Actor and wait for it to finish
run = client.actor("celebrated-quadraphonic/crates-io-scraper").call(run_input=run_input)

# Fetch and print Actor results from the run's dataset (if there are any)
print(f"💾 Check your data here: https://console.apify.com/storage/datasets/{run.default_dataset_id}")
for item in client.dataset(run.default_dataset_id).iterate_items():
    print(item)

## CLI example

```bash
echo '{
  "category": "",
  "includeVersions": true,
  "keyword": "",
  "maxCrates": 50,
  "maxVersionsPerCrate": 5,
  "searchQuery": "web framework",
  "sortBy": "downloads"
}' |
apify call celebrated-quadraphonic/crates-io-scraper --silent --output-dataset

```

## MCP server setup

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