Getting Started
Create an Hgraph account, set up your first organization and project, and get your API key.
Endpoints & Authorization
Hgraph endpoint structure and authentication. One API key works across every network and every API — GraphQL, REST, JSON-RPC, and MCP.
Playgrounds
Test GraphQL, JSON-RPC, and SQL queries against live Hedera data in the Hgraph App's built-in playgrounds.
Rate Limits & Quotas
Hgraph rate limits, monthly request quotas, and the plan gates that decide which APIs and data sets your key can reach.
