Tickdb Unified Realtime Marketdata Api

TickDB is an AI-native real-time market data API delivering stock quotes, forex, crypto, indices, and commodities for US, HK, and A-share markets. Designed for quantitative traders, AI researchers, and developers, it provides multiple interfaces including REST API, WebSocket, CLI, MCP (Model Context Protocol), and a Python SDK. The platform emphasizes data integrity and auditability: every price tick includes metadata such as market state (pre-market, regular, after-hours), timestamp semantics, and source timestamps, enabling users to resolve multi-source conflicts and trace data gaps. Key features include Level 1 and Level 2 order book data, historical K-lines with configurable periods (1m, 5m, 1h, 1d, etc.), and real-time streaming with automatic reconnection and gap detection. The blog highlights practical data validation techniques—like verifying symbol stability, time range completeness, and OHLCV consistency—critical for reliable backtesting. TickDB also supports physical and adjusted prices (split/dividend) and provides audit trails for compliance. Targeted at production systems requiring trustworthy data, TickDB is not a trading platform or signal generator but a data infrastructure layer. It distinguishes itself from competitors like Polygon.io and IEX Cloud by focusing on data provenance and chain-of-custody, making it a solid choice for institutions that need verifiable data for algorithmic strategies or AI agent integration.
