🔮 Metaculus Questions Scraper

🚀 Export Metaculus forecasting questions in seconds, including community predictions, prediction counts, categories, and resolution dates, straight from the public api2 endpoint.

🕒 Last updated: 2026-05-29 · 📊 12 fields per record · 50,000+ Metaculus questions · Crowdsourced forecasting

The Metaculus Questions Scraper turns the Metaculus public api2/questions/ endpoint into a clean dataset. It walks the cursor-paginated feed, filters by status and free-text search, and emits one row per question with the community median prediction, category, and timing.

📋 What the Metaculus Questions Scraper does

• Calls https://www.metaculus.com/api2/questions/ with status, search, and ordering filters.
• Walks pagination until maxItems is reached.
• Extracts community median prediction, prediction count, categories, close & resolve times.
• Exports as CSV, Excel, JSON, JSONL, XML, RSS, or HTML.

💡 Why it matters: Metaculus is the largest serious forecasting community on the internet. Their community predictions are battle-tested calibration sources.
