Nostr Metadata Updater

The Nostr Metadata Updater is a containerized web application powered by FastAPI and asyncio. It queries and updates metadata on Nostr relays in real-time. The app checks for outdated events (kind 0) on various relays and rebroadcasts the latest metadata to those relays found to have outdated events.

This application leverages FastAPI to provide a web-based interface and uses asyncio to handle asynchronous queries to the relays, ensuring high performance and responsiveness.
