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 ## Hacker News Scraper — Apify Actor Extract stories from Hacker News with filtering by points and keywords. ### Features - Fetch **top**, **new**, or **best** stories - Filter by **minimum points** score - Filter by **keywords** in story titles (comma-separated) - Structured output: title, URL, points, author, comment count, timestamp - Uses official **Firebase API** — no scraping, no blocks ### Input | Field | Type | Default | Description | |-------|------|---------|-------------| | `storyType` | enum | `top` | Story feed: top / new / best | | `limit` | int | 30 | Max stories to fetch (≤100) | | `minPoints` | int | 0 | Minimum upvotes filter | | `keywords` | string | — | Comma-separated keywords (e.g. `AI,Python,YC`) | ### Output (one row per story) ```json { "id": 43254321, "title": "Show HN: Example Project", "url": "https://example.com", "author": "username", "points": 342, "comment_count": 87, "hn_url": "https://news.ycombinator.com/item?id=43254321", "type": "story", "time": 1748217600 } ```` ### Use Cases - 📰 **Tech trend monitoring** — what's trending on HN right now - 🏢 **Startup intelligence** — track Show HN launches - 🤖 **AI training data** — collect curated tech news content - 📊 **Competitive analysis** — monitor developer sentiment ### Example ```bash ## CLI via Apify API curl -X POST "https://api.apify.com/v2/acts/wsgcjj~hacker-news-scraper/runs" \ -H "Content-Type: application/json" \ -d '{"storyType":"top","limit":10,"minPoints":100,"keywords":"AI,LLM"}' ``` ### Limits - 100 stories max per run (Firebase API limit) - Free API — no API key or proxy needed # Actor input Schema ## `tags` (type: `string`): Filter by tag(s), semicolon-separated (e.g. 'python;fastapi' or just 'python'). Leave empty for all. ## `sort` (type: `string`): Sort criterion for results ## `time_range` (type: `string`): Time window for the chosen sort ## `min_score` (type: `integer`): Minimum question score (upvotes minus downvotes) ## `limit` (type: `integer`): Maximum number of questions to return (max 100 per API call) ## Actor input object example ```json { "tags": "", "sort": "votes", "time_range": "month", "min_score": 0, "limit": 30 } ``` # 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 = {}; // Run the Actor and wait for it to finish const run = await client.actor("wsgcjj/stackoverflow-questions").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 📖?
