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 ## Crates.io Rust Crate Metadata Scraper — Rust Package Intelligence Extract comprehensive metadata for any Rust crate on crates.io, the official Rust package registry. This Actor fetches crate details including download statistics, version history, dependency information, owner details, and license data directly from the crates.io public API. No browser rendering required — fast, reliable, and cost-effective. ### Use Cases - **Dependency Audit** — Analyze crate metadata, licenses, and version stability before adding dependencies to your Cargo.toml - **Package Research** — Compare download counts, recent activity, and maintainer engagement across Rust libraries - **Security Scanning** — Monitor crate versions and yanked status for vulnerable or deprecated packages - **Market Intelligence** — Track trending Rust crates by total and recent download metrics - **CI/CD Integration** — Validate crate metadata in automated build and release pipelines ### Input | Field | Type | Required | Description | |-------|------|----------|-------------| | `crateNames` | Array | Yes | List of Rust crate names from crates.io | | `includeVersions` | Boolean | No | Include full version history for each crate (default: false) | | `includeOwners` | Boolean | No | Include crate owner usernames (default: false) | | `proxyConfiguration` | Object | No | Proxy configuration for requests | #### Example Input ```json { "crateNames": ["serde", "tokio", "reqwest", "clap", "axum"], "includeVersions": false, "includeOwners": false } ```` ### Output The Actor outputs a dataset with the following fields for each crate: ```json { "name": "serde", "description": "A generic serialization/deserialization framework", "version": "1.0.219", "downloads": 427654321, "recentDownloads": 15234867, "repository": "https://github.com/serde-rs/serde", "documentation": "https://docs.rs/serde", "homepage": "", "license": "MIT OR Apache-2.0", "keywords": ["serde", "serialization", "deserialization"], "categories": ["encoding", "no-std", "no-std::no-alloc"], "createdAt": "2015-05-15T04:14:55+00:00", "updatedAt": "2025-03-05T02:42:27+00:00", "maxVersion": "1.0.219", "newestVersion": "1.0.219", "maxStableVersion": "1.0.219", "numVersions": 142, "yanked": false, "url": "https://crates.io/crates/serde" } ``` ### Pricing Pay per event: **$0.001 USD per crate extracted**. ### Limitations - Crate names must match exactly as listed on crates.io - Download statistics reflect total historical and recent (90-day) downloads - Version history can be large for mature crates — use `includeVersions` sparingly - crates.io API requires a descriptive User-Agent header and may rate limit very high volume usage ### FAQ **Q: Can I search for crates by keyword?** A: This Actor requires exact crate names. Use the crates.io website search to find crate names first. **Q: What if a crate does not exist?** A: The Actor logs a warning and continues processing the remaining crates. **Q: Is authentication required?** A: No. crates.io provides a public API with no authentication needed. ### Changelog - **v1.0.0** — Initial release # Actor input Schema ## `crateNames` (type: `array`): List of Rust crate names from crates.io (e.g., serde, tokio, reqwest) ## `includeVersions` (type: `boolean`): Include full version history for each crate (can be large) ## `includeOwners` (type: `boolean`): Include crate owner usernames ## `proxyConfiguration` (type: `object`): Proxy settings for requests ## Actor input object example ```json { "crateNames": [ "serde", "tokio", "reqwest", "clap", "axum" ], "includeVersions": false, "includeOwners": false, "proxyConfiguration": { "useApifyProxy": true } } ``` # Actor output Schema ## `results` (type: `string`): No description ## `stats` (type: `string`): No description # 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 '' with your token const client = new ApifyClient({ token: '', }); // Prepare Actor input const input = { "crateNames": [ "serde", "tokio", "reqwest", "clap", "axum" ], "includeVersions": false, "includeOwners": false, "proxyConfiguration": { "useApifyProxy": true } }; // Run the Actor and wait for it to finish const run = await client.actor("klondikeking/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); }); // 📚 Want to learn more 📖?
