This API provides direct interaction with the Hedera Blockchain on the testnet, allowing users to create topics (identified by unique topic IDs), post events to these topics, retrieve past events for a specific topic, and view a full list of created topics. Users can verify all API inputs and interactions on the Hedera IO dashboard by visiting Hashscan. Simply enter a topic ID in the search bar at Hashscan to view the complete event ledger associated with that topic.
Note: The backend Flask application that interfaces with the Hedera Blockchain is hosted on Render's free tier service and deployed via Docker containers, which may take approximately 50 seconds to boot up if inactive. Please click on "GET LIST OF TOPICS BY ID" and wait for the response to use the application.
