Why this is the best choice for developers
Complete data capture
Unlike many providers who filter or sample data, we capture every message from the exchange with nanosecond-precision timestamps, ensuring no information loss and preserving the exact sequence of market events.
Intelligent processing pipeline
Our system normalizes and indexes this raw data without sacrificing any information detail. We maintain all original values, flags, and indicators that provide crucial context for sophisticated analysis.
Flexible query architecture
REST API allows you to query this comprehensive dataset using multiple parameters: by symbol (individual securities), by date (specific historical dates), by message type (admin, quotes, trades, or order book events), and by specific event types (e.g., trading halts, auction information, short sale restrictions).
Optimized response delivery
When you make an API request, our system authenticates your API key, processes your specific query parameters and retrieves the precise data subset you need from our optimized storage. You receive a consistent, well-structured JSON response.
Multiple data depth options
Depending on your needs, you can access: level 1 data (NBBO quotes), level 2 data (price level aggregation), level 3 data (individual orders), trade executions with detailed condition flags, and administrative messages with complete market context.
