Stellar RPC Provider for Production Apps
Managed Stellar API and RPC infrastructure for developers building wallets, analytics apps, fintech products, and tokenization platforms. Skip the node operations and start building.
Managed Stellar Infrastructure
LumenQuery operates the full Stellar stack so you do not have to. Our infrastructure includes Horizon API servers, Soroban RPC nodes, PostgreSQL databases, Redis caching, and monitoring with Prometheus and Grafana.
Monitored 24/7 with automated failover and alerting
Sub-50ms for cached data, sub-300ms for live queries
Infrastructure scales with your traffic, no manual intervention
Everything You Need in One Provider
Most Stellar RPC providers stop at raw API access. LumenQuery gives you the full developer platform.
Horizon REST API
Full access to accounts, transactions, payments, assets, ledgers, operations, effects, offers, and trade aggregations. Supports SSE streaming for real-time events.
Horizon API detailsSoroban JSON-RPC
Invoke smart contracts, simulate transactions, query contract events, and browse contract storage. Full JSON-RPC 2.0 compliant endpoint for Soroban development.
Soroban RPC detailsNetwork Analytics
Pre-built analytics dashboards for network metrics, token velocity, whale movements, and smart contract activity. Available as both UI and API.

What is a Stellar RPC provider?
A Stellar RPC provider gives developers managed access to Stellar network APIs without running their own infrastructure. This includes Horizon REST API for querying blockchain data and Soroban RPC for smart contract interactions. LumenQuery handles node operation, database management, and protocol upgrades.
Why should I use a managed Stellar RPC provider instead of self-hosting?
Self-hosting Stellar infrastructure requires running Stellar Core, PostgreSQL, and Horizon or Soroban RPC servers. This means server costs starting at $200/month, database tuning, disk management for the growing ledger, and manual protocol upgrades every few months. A managed provider eliminates this overhead.
What APIs does LumenQuery provide?
LumenQuery provides Horizon REST API (accounts, transactions, payments, assets, ledgers, operations, DEX), Soroban JSON-RPC (smart contract invocation, simulation, event queries), analytics APIs (network metrics, token velocity, whale tracking), natural language query capabilities, and portfolio intelligence.
What uptime does LumenQuery guarantee?
LumenQuery targets 99.9% uptime for all API endpoints. Infrastructure is monitored with Prometheus and Grafana, with automated alerting for latency spikes, error rate increases, and resource usage anomalies.
How fast are LumenQuery API responses?
Most API requests complete in under 300ms. Frequently accessed data is served from Redis cache with sub-50ms response times. Streaming endpoints (SSE) deliver events within seconds of ledger close.
Does LumenQuery support Soroban smart contracts?
Yes. LumenQuery provides both Horizon API for general Stellar queries and Soroban JSON-RPC for smart contract development. You can simulate transactions, invoke contracts, query contract events, and explore contract storage through a single provider.
