📄️ GraphQL API Overview
Hgraph provides GraphQL API endpoints for accessing our Hedera mirror node and various subscription plans for production access (including free access for experimenting). If you're new to GraphQL, the official documentation is a good starting point.

📄️ Subscriptions
The Hgraph SDK includes built-in GraphQL subscription management capabilities, simplifying the process of handling and interacting with subscriptions. This feature encapsulates all active subscriptions and their lifecycle control within the Client. WebSockets are utilized by the GraphQL API to enable subscriptions.
