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 ## Y Combinator Companies Scraper Scrape startups from the public [Y Combinator company directory](https://www.ycombinator.com/companies). ### Use cases - Build a YC startup database - Lead-gen / sales prospecting on YC alumni - Track YC trends by batch / industry - Find competitors in your space ### Input - `query` — free-text search - `batch` — filter by batch (e.g. `Winter 2024`, `Summer 2023`) - `industry` — filter by industry (e.g. `Fintech`, `B2B`) - `status` — Active / Acquired / Public / Inactive - `maxItems` — number of companies (1–2000) ### Output Each item: `{ id, name, slug, one_liner, long_description, batch, status, stage, team_size, industries, tags, regions, all_locations, website, launched_at, top_company, isHiring, url, scrapedAt }` ### Pricing **$0.004 / company returned.** ### How it works Calls the public YC search backend (Algolia, app `45BWZJ1SGC`, index `YCCompany_production`). The same endpoint powers the official ycombinator.com/companies UI — credentials are public read-only keys. # Actor input Schema ## `query` (type: `string`): Free-text search across company name, description, founders. ## `batch` (type: `string`): Filter by YC batch (e.g. 'Winter 2024', 'Summer 2023'). Empty = all batches. ## `industry` (type: `string`): Filter by industry (e.g. 'Fintech', 'B2B', 'Healthcare'). ## `status` (type: `string`): Company status filter. ## `maxItems` (type: `integer`): Max companies to return. $0.004 per company. ## Actor input object example ```json { "query": "", "batch": "", "industry": "", "status": "", "maxItems": 25 } ```` # Actor output Schema ## `results` (type: `string`): Dataset items # API You can run this Actor programmatically using our API. Below are code examples in JavaScript, Python, and CLI, as well as the OpenAPI specification and MCP server setup. ## JavaScript example ```javascript import { ApifyClient } from 'apify-client'; // Initialize the ApifyClient with your Apify API token // Replace the '' with your token const client = new ApifyClient({ token: '', }); // Prepare Actor input const input = { "maxItems": 25 }; // Run the Actor and wait for it to finish const run = await client.actor("gio21/ycombinator-companies-scraper").call(input); // Fetch and print Actor results from the run's dataset (if any) console.log('Results from dataset'); console.log(`💾 Check your data here: https://console.apify.com/storage/datasets/${run.defaultDatasetId}`); const { items } = await client.dataset(run.defaultDatasetId).listItems(); items.forEach((item) => { console.dir(item); }); // 📚 Want to learn more 📖?
