How It Works
LumenQuery's query engine bridges the gap between human language and blockchain data.
1. Ask a Question
Type your query in plain English. No need to know table schemas or SQL syntax.
2. We Translate
Our engine parses your intent and generates an optimized query against our real-time Stellar index.
3. Query Blockchain
Execute against indexed Stellar data—transactions, accounts, assets, and more.
4. Get Results
View data as interactive tables, time-series charts, or exportable JSON.
Example Queries
Click any example to try it. LumenQuery understands the questions that matter to blockchain analysts, developers, and operators.
Key Features
Everything you need to explore blockchain data without writing code.
Natural Language → SQL Translation
Our query engine converts your questions into optimized SQL, executed against a fully-indexed Stellar dataset. View the generated SQL anytime—learn as you query.
Real-Time Blockchain Indexing
Data refreshes every 5 seconds. Query the latest ledgers, not stale snapshots. Monitor live transactions and catch network anomalies as they happen.
Interactive Charts & Dashboards
Every result is interactive. Click a wallet to explore its history. Select a time range to zoom in. Build custom views without code.
Export Results via API
Every query generates an API endpoint. Fetch JSON results programmatically, integrate with your data pipelines, or embed live data in your applications.
Multi-Dataset Support
Query across transactions, operations, effects, accounts, assets, trades, and ledgers. Join data naturally—we handle the complexity.
Developer Friendly
LumenQuery is built for developers who want transparency and control.
SQL Visibility
Every query shows its SQL equivalent. Copy, modify, or run raw SQL directly.
API Access
Programmatic access to all query results. Build dashboards, alerts, and automated reports.
Data Pipelines
Export to CSV, JSON, or stream to your data warehouse. Connect to BigQuery, Snowflake, or Postgres.
