Why switch

Why developers switch from Alpha Vantage

  • WebSocket streaming — Alpha Vantage is REST-only

    Alpha Vantage has no WebSocket endpoint. Every update requires a new HTTP request, which means your app is polling on a timer. Real Market API's WebSocket connection pushes new candle ticks and price updates the moment they form.

  • 5,000 free requests vs. 25 per day

    Alpha Vantage's free API key is limited to 25 requests per day — enough for a demo, not a development workflow. Real Market API's free plan includes 5,000 monthly requests with live data, covering several weeks of active testing.

  • Live data — not 15–20 minute delayed

    Alpha Vantage free data is delayed by 15–20 minutes. The premium plan at $50/mo unlocks near-real-time. Real Market API serves sub-150ms live data from the free plan onward — no tier upgrade needed just to see current prices.

  • Native MCP Server — Alpha Vantage has none

    Alpha Vantage has no Model Context Protocol support. Real Market API's MCP Server exposes 33 tools — prices, candles, volatility, indicators — that any LLM agent can call natively without a custom HTTP wrapper.

Pricing note
