1. Acts as a cache for on-chain data. It stores the metadata from the smart contract events off-chain in a Typesense database.
2. Monitors events: It continually checks for MetadataCreated and MetadataUpdated events, processing these events and updating them in the database.
3. Serves as an API: It provides a REST API that fetches data from the off-chain datastore.
4. Offers easy query access: The API provides a convenient method to access metadata without needing to scan the blockchain.
