The short version

  • Each has a real cost: CoinMarketCap the free Basic plan gives historical data going back only 60 seconds, so it cannot answer any question about the past; Polygonscan the PolygonScan API page now redirects to Etherscan's unified multichain API pricing, so Polygon data is bought under Etherscan plans rather than a PolygonScan-specific one
  • They diverge on capability: CoinMarketCap covers Price Tracking, Polygonscan covers Block Explorer.
  • Prices and features above were last checked on 30 August 2026.
