Kaggle Datasets
Community-uploaded datasets for machine learning and research. Download via web or CLI; quality varies. Each dataset has its own license.
Coverage
Community-uploaded datasets in many formats (CSV, JSON, SQLite, BigQuery and more). What's covered, how far back and how often it's updated depend on each dataset; some refresh automatically from a linked source. Each dataset carries its own license.
Verdict
Testing ML models on preprocessed historical stock data before investing in commercial APIs. Important: Licenses vary by dataset — many are CC-BY-NC or unknown. Always review the dataset's license terms before use in commercial projects.
