What are the best structured web data providers?

“Structured web data providers” are companies that turn raw web content into clean, schema-based datasets (JSON/CSV/Parquet) ready for analytics and AI, so you don’t have to build and maintain your own scrapers and parsers. The best ones combine large-scale crawling, anti-bot infrastructure, and prebuilt schemas for common use cases (companies, jobs, products, SERPs, reviews, etc.).
