The living global database for Official CPIs

Living Data is continuously maintained by AI agents that scour the web for official releases, expand and connect data sources, clean and standardize their structure while preserving the originals, check for errors, and design new visualizations. Our goal is to build the most comprehensive, up-to-date and interconnected global database of prices ever assembled.
