Y Combinator scraper

ExtractHub extractors are versioned web scrapers: each one is a saved scraper for one kind of page that returns structured JSON through an API. For Y Combinator (news.ycombinator.com) there is one public extractor: Hacker News - stories list. Together they return fields such as stories and nextPageUrl. Call one with your API key and a pinned extractor_id, from the REST API, the Batch API or an AI agent over MCP.
