Metin2 Market

Know the market before you buy the sword.

That equipment listing might be a bargain. Or it might just have an ambitious seller. Metin2 Market turns listings into price history, bonus comparisons, alerts, and possible deal signals.

A configurable JSON feed supplies item metadata and market snapshots. An ETL pipeline cleans the data and loads a PostgreSQL warehouse, which a FastAPI service exposes to the React dashboard.

More than a price tag

Track selected items, explore prices by server and enchantment, and compare how equipment bonuses affect value. Searchable listings connect the analysis back to the market.

A warehouse behind the shop

Shared item and time dimensions connect price-history, equipment, and undervaluation facts. Snapshot fingerprints help limit ingestion to added or changed rows.

Bring your own feed

External synchronization starts disabled. The project expects a configured, authorized source; the dashboard is an analysis tool, not a promise of profitable trades.
