## Pricing

from $6.80 / 1,000 results

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.

## Crates.io Rust Packages Scraper - Downloads & Versions

> Search Rust crates by keyword and export clean structured data: download counts, latest version with license, minimum supported Rust version, package size and publish date, maintainers with their GitHub handles, repository, documentation, categories and keywords. Ideal for Rust ecosystem research, supply-chain review and dependency discovery.

### Who is it for

| Use case | Who benefits |
|---|---|
| Rust ecosystem research | Analysts tracking popular crates and trends |
| Dependency discovery | Engineers finding crates for a given need |
| Package comparison | Teams ranking crates by downloads and recency |
| Dashboards | Builders feeding crate stats into their own apps |

### How to use it

1. Enter a **search keyword** (for example `serialization` or `async runtime`).
2. Set **Max Items**.
3. Run it and export as JSON, CSV or Excel, or pull it through the Apify API.

### Frequently Asked Questions

**How are results ordered?**
Crates are returned by download count so the most used ones come first.

**Which fields are numeric?**
Downloads, recent downloads and version count are parsed as numbers so you can sort and filter directly.

**Can I collect more than one page?**
Yes. Set Max Items higher and the scraper pages through the results for you.

**How fresh is the data?**
Download counts and versions are read live at run time, so each record reflects the moment of the run (see observedAt).

### Export, API and AI agents (x402 + MCP)

Export the scraped data to **JSON, CSV or Excel**, pull it as a **dataset** through the Apify **API**, or wire it into your app with **no code**. This web scraper and data extractor also works for bulk data extraction and scheduled runs.

For AI agents: this Actor is available on **x402**, Apify's agentic payment standard built with Coinbase. An AI agent can discover, pay for and run it on its own with a funded wallet and a single HTTP request: no account, no subscription, no API key and no human in the loop. It also runs as an **MCP** tool inside Claude, Cursor and other AI clients out of the box. Learn more about [x402 agentic payments on Apify](https://docs.apify.com/platform/integrations/x402).
