All open datasets
Explore open, documented datasets for analysis and machine learning, with clear licences, JSON API access, and Parquet downloads.
7 datasets of 27
Every dataset here is published as immutable Apache Parquet versions with a documented column schema, column profiles, an explicit licence and a named publisher. Read the schema and a sample of real rows without an account; sign up free to run bounded JSON queries or download the whole snapshot for training, backtesting or analysis. Agents can do the same over the Model Context Protocol at /api/mcp, or read /llms-full.txt for the whole catalogue in one file.
