Possible disadvantages

    Free or lower-priced subscription plans may come with restrictive rate limits and API call caps, which can hinder high-frequency use cases or applications with heavy data needs.

  • Reliability and Uptime Concerns
    Being a smaller or less-established provider, there may be concerns about long-term reliability, uptime guarantees, and support responsiveness compared to well-known enterprise data services like Bloomberg or Refinitiv.

Real-time Market API started as a side project to solve a simple problem: getting reliable, real-time market data across different asset classes was messy, expensive, and fragmented.

Instead of stitching together multiple providers, the goal was to build a single, clean API that delivers not just data—but actionable insights.

Over time, it evolved from basic price feeds into a signal-driven platform, shaped by real needs from trading, monitoring, and automation use cases.
