Learn moreWhy Data Fidelity Matters
Category-appropriate capture rates with sub-100ms end-to-end latency from exchange event to ClickHouse persistence.
Event-Driven Capture vs Polling
Traditional data providers poll APIs at fixed intervals (1s, 5s, 30s), missing critical microstructure events between samples. Our pipeline uses aggressive 50ms polling combined with WebSocket event streams for crypto markets (20 Hz), with optimized 2 Hz capture for sports and 1 Hz for economic indicators. The result: category-appropriate capture rates with sub-100ms end-to-end latency from exchange event to ClickHouse persistence.
AI Agents Meet Orderbook Data
Connect Claude, GPT, or custom agents to live market state over the Model Context Protocol.
What are the current NBA championship odds and NYC weather market?
{
"tool": "list_markets",
"params": {
"category": ["sports", "weather"],
"filter": "NBA championship, NYC temperature"
}
}I found 6 active NBA championship markets and 1 NYC daily temperature market. NBA Championship: The current frontrunner shows bid 0.32 / ask 0.34 with deep liquidity (18,500 contracts on the bid side). Three other teams are trading between 0.08-0.15. NYC Weather: The "above 72F" outcome for today is at mid price 0.61, with a tight spread of 0.02. Weather markets typically see increased volume closer to settlement time (6 PM ET).
