Hgraph Platform
Hgraph is a data infrastructure and intelligence platform for blockchain networks. Self-serve access to the same infrastructure that powers enterprise engagements.
Why Hgraph
- Owned infrastructure - Bare-metal nodes we operate directly. Not resold cloud infrastructure. Lower latency, higher reliability, full control.
- Battle-tested - Every feature was built to solve a real problem for a real client. The platform improves with every production engagement.
- One vendor, full stack - Infrastructure, APIs, intelligence, and dashboard in one platform. No stitching together multiple providers.
- Team behind the platform - Senior engineers who build and operate the systems you depend on. Not a faceless API provider.
The platform is built on four interconnected layers:
Infrastructure
Bare-metal node infrastructure built for production workloads. High availability, low latency, consistent performance. Hgraph runs the nodes and indexers so your team never has to.
- Node operations - Bare-metal nodes operated directly for production uptime across supported networks
- Data indexing - Historical and real-time blockchain data indexed and queryable. Terabytes of chain history, ready when you need it.
- Token Indexer - ERC token balances, transfers, metadata, and NFT ownership from a single endpoint. Discovers contracts automatically.
- Multi-chain support - Hedera in production. Ethereum coming soon with early access. Expand to additional chains without re-architecting your stack.

APIs
One integration point for every supported network. Access Hedera data today and Ethereum soon through the interface that fits your stack. All core APIs are available on all plans, including the free tier.
- GraphQL API - Flexible queries and real-time subscriptions via WebSocket
- REST API - Standard RESTful endpoints for account balances, transactions, tokens, and network state
- JSON-RPC - EVM-compatible interface for Ethereum tooling and wallets
- Hgraph SDK - Client libraries for TypeScript with typed, documented APIs
- WebSocket Subscriptions - Real-time event streams for transactions, token transfers, and state changes
- ERC Token Data - ERC-20 and ERC-721 token data on Hedera
Intelligence
Connect AI models directly to indexed blockchain data. Agents discover, query, and pay for data without custom integration.
- MCP Server - Published to public registries. Add it to your agent's tool list and start querying. No custom integration needed. Works with Claude, ChatGPT, and custom models.
- AI Data Agent - Natural language queries against indexed blockchain data. No setup, no API key.
- x402 Payment Protocol - Pay-per-query access built into every endpoint. Agents pay for data via standard HTTP headers without signup or human approval.
- Observability - Built-in dashboards for agent activity, query volume, error rates, and API latency.
Dashboard
Manage everything from one place. Create projects, monitor usage, test queries in built-in playgrounds, and scale your plan when ready.
- API key management - Create, rotate, and scope API keys per project. Track usage per key.
- Usage analytics - Monitor request volume, latency, and error rates across all your endpoints.
- Built-in playgrounds - Test GraphQL and JSON-RPC queries against live data without leaving the dashboard.
- Billing and plans - Manage your plan, usage, and invoices in one place.
