## What it does

ragalgo delivers normalized metric scores from 0 to 100 alongside market zones instead of raw pricing streams. It targets equities across the US and South Korea, as well as crypto assets. Since the system calculates data after trading sessions conclude, assistants work with verified summaries rather than intraday price swings.

The underlying data pipeline ingests market news and computes ratings, publishing a consolidated snapshot daily at 18:00 KST. Running queries requires a valid `RAGALGO_API_KEY`. Attempting to use this server for sub-second day trading will fail, because its design deliberately excludes live order book feeds.
