RealMarketAPI vs Polygon.io

Real Market API vs Polygon.io — more asset classes, lower entry price

Polygon's free tier gives you 5 API calls/minute on 15-minute-delayed data. Real Market API's free plan delivers live data with no per-minute throttle — and all Forex, Metals, Oil, and Indices are included in every paid plan, not sold as separate bundles.

Why switch

Why developers switch from Polygon.io

  • Free plan with live data, not delayed snapshots

    Polygon's free tier caps you at 5 API calls/min and returns 15-minute-delayed data. Real Market API's free plan has a monthly request quota (5,000 req/mo) with live sub-150ms data — no per-minute throttle.

  • Forex and Metals included — not a paid add-on

    Polygon sells Forex, Options, and Indices as separate data bundles on top of the base plan price. Real Market API includes Forex (14 pairs), Gold, Silver, Platinum, Oil, and global Indices on every paid tier.

  • MCP Server for AI workflows — Polygon has none

    Polygon offers no Model Context Protocol endpoint. Real Market API ships a native MCP server so your LLM agent can call live prices, candles, and indicators as first-class tools without any custom proxy.

  • One plan, all assets — from $4.99/mo

    Polygon Starter is $29/mo for US stocks only. Forex, options, and crypto are priced separately. Real Market API's $4.99 Starter covers Forex, Metals, Crypto, Stocks, Oil, and Indices — no bundles.
