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 - JSON-RPC on Hedera and 20+ EVM networks. Indexed data on Hedera in production, Ethereum in beta. Expand to additional chains without re-architecting your stack.

APIs​

One integration point for every supported network, 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, with Ethereum in beta

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.

Pricing​

Every plan, including Free, reaches all core APIs. Plans differ in throughput, project and key counts, and whether ERC and ecosystem data are reachable programmatically.
