Short summary
A technical comparison of three market data APIs — AllTick, Bloomberg, and Alpha Vantage — evaluating data granularity, protocol support, rate limits, and historical depth. Includes production-ready Python code snippets for REST integration. AllTick is positioned as a balanced option for individual builders, Bloomberg for institutional teams, and Alpha Vantage for prototyping.
- •AllTick offers tick-level data with REST/WebSocket at 100 req/min free tier
- •Bloomberg provides institutional-grade depth with sub-10ms latency but no free tier
- •Alpha Vantage suits lightweight prototyping with 5 req/min and no native WebSocket
