Research topic taxonomy from OpenAlex with subfields, fields, domains and Wikipedia links. Built for analysts, researchers and product teams who need clean, structured records without writing custom scrapers.

📋 What the OpenAlex Topics Scraper does

• Walks public OpenAlex surfaces and follows pagination
• Pushes one clean record per item with stable field names
• Adds an ISO timestamp on every record
• Surfaces errors as records rather than failing the whole run
• Auto-limits free runs to 10 records (preview), paid runs up to 1,000,000

💡 Why it matters Structured records are easier to wire into dashboards, warehouses and notebooks than raw scraped pages.
