# Crates.io Rust Packages Scraper (`geodetic_marigold/cratesio-scraper`) Actor Busca crates (pacotes Rust) no crates.io por palavra-chave e devolve dados estruturados: downloads totais e recentes, versões (estável/última), repositório, documentação, homepage e datas. Consumer da API pública oficial — sem browser, estável e rápido. Pronto para planilha, BI ou IA. - **URL**: https://apify.com/geodetic\_marigold/cratesio-scraper.md - **Developed by:** [Antonio Fernando Rincon de Mendonça](https://apify.com/geodetic_marigold) (community) - **Categories:** Developer tools, Automation - **Stats:** 2 total users, 1 monthly users, 100.0% runs succeeded, 0 bookmarks - **User rating**: No ratings yet ## Pricing Pay per usage This Actor is paid per platform usage. The Actor is free to use, and you only pay for the Apify platform usage, which gets cheaper the higher subscription plan you have. Learn more: https://docs.apify.com/platform/actors/running/actors-in-store#pay-per-usage ## What's an Apify Actor? 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 Packages Scraper > Busca crates (pacotes Rust) no **crates.io** por palavra-chave e devolve dados > estruturados — downloads, versões, repositório, docs e datas — via a **API > pública oficial**. Sem browser, sem API key, sem proxy. ### Por que usar Consome a API REST oficial do crates.io (`/api/v1/crates`), então o resultado é **estável, tipado e rápido** — nada de seletores HTML que quebram. Exporte em **JSON, CSV ou Excel** (ou puxe via **API** e **MCP**) para análise de ecossistema Rust, due diligence de dependências, market research de pacotes ou pipelines de IA. ### Casos de uso - Mapear os crates mais baixados de um tema (ex.: `async`, `web framework`, `cli`) - Monitorar versões e datas de atualização de dependências - Descobrir repositórios e documentação de um conjunto de pacotes - Alimentar agentes de IA com dados frescos do ecossistema Rust ### Como rodar 1. Preencha `searchQuery` (ex.: `serde`) e clique em **Start**. 2. Acompanhe o run — os crates aparecem no Dataset em tempo real. 3. Exporte em **JSON / CSV / Excel** ou consuma via **API** e **MCP**. 4. (Opcional) Agende execuções recorrentes no **Scheduler** da Apify. ### Input | Campo | Tipo | Obrigatório | Descrição | |---|---|---|---| | `searchQuery` | string | sim | O que procurar no crates.io. Ex.: `serde`, `tokio`, `web framework`. | | `maxItems` | integer | — | Máximo de crates a coletar (1–5000). Padrão 100. | | `sort` | string | — | `downloads`, `recent-downloads`, `recent-updates`, `new`, ou vazio (relevância). | #### Exemplo de input ```json { "searchQuery": "serde", "maxItems": 20, "sort": "downloads" } ```` ### Output Cada item no Dataset: ```json { "name": "serde", "description": "A generic serialization/deserialization framework", "url": "https://crates.io/crates/serde", "downloads": 500000000, "recentDownloads": 50000000, "maxVersion": "1.0.210", "newestVersion": "1.0.210", "maxStableVersion": "1.0.210", "homepage": "https://serde.rs", "documentation": "https://docs.rs/serde", "repository": "https://github.com/serde-rs/serde", "createdAt": "2014-12-05T20:20:39.487616+00:00", "updatedAt": "2024-09-01T12:00:00.000000+00:00", "exactMatch": true, "searchQuery": "serde", "scrapedAt": "2026-06-28T00:00:00.000Z" } ``` ### Use com agentes de IA (MCP) Este Actor é **compatível com o [Apify MCP Server](https://docs.apify.com/platform/integrations/mcp)** — agentes de IA (Claude, ChatGPT, Cursor) podem chamá-lo diretamente: conecte o MCP Server, o agente descobre o Actor pelo nome `cratesio-scraper`, lê o `input_schema` e chama com o input desejado. O `dataset_schema` garante output tipado e estável. ### Preço — Pay Per Event | Evento | Preço | |---|---| | `package-scraped` | $0.005 por crate retornado | Você paga **apenas pelo resultado**: runs que não acham nada custam **zero**. ### FAQ - **Preciso de API key ou login?** Não — a API do crates.io é pública. - **Em quais formatos exporto?** JSON, CSV, Excel, HTML table, ou via API/MCP. - **Dá para agendar?** Sim — use o Scheduler da Apify para coletas recorrentes. - **O formato do output muda entre execuções?** Não — o `dataset_schema` mantém os campos estáveis. - **Respeita o crates.io?** Sim — User-Agent identificável e ~1 requisição/segundo, conforme a política de crawler do crates.io. ### Changelog - **0.1** — primeira versão: consumer da API oficial do crates.io. # Actor input Schema ## `searchQuery` (type: `string`): O que procurar no crates.io. Ex.: "serde", "tokio", "web framework", "async". ## `maxItems` (type: `integer`): Limite superior de crates a coletar. Valores altos aumentam o tempo do run (a API entrega 100 por página, ~1 página/segundo). ## `sort` (type: `string`): Como ordenar os resultados. Em branco = relevância padrão do crates.io. ## Actor input object example ```json { "searchQuery": "serde", "maxItems": 100, "sort": "" } ``` # API You can run this Actor programmatically using our API. Below are code examples in JavaScript, Python, and CLI, as well as the OpenAPI specification and MCP server setup. ## JavaScript example ```javascript import { ApifyClient } from 'apify-client'; // Initialize the ApifyClient with your Apify API token // Replace the '' with your token const client = new ApifyClient({ token: '', }); // Prepare Actor input const input = { "searchQuery": "serde" }; // Run the Actor and wait for it to finish const run = await client.actor("geodetic_marigold/cratesio-scraper").call(input); // Fetch and print Actor results from the run's dataset (if any) console.log('Results from dataset'); console.log(`💾 Check your data here: https://console.apify.com/storage/datasets/${run.defaultDatasetId}`); const { items } = await client.dataset(run.defaultDatasetId).listItems(); items.forEach((item) => { console.dir(item); }); // 📚 Want to learn more 📖?
