CoinMarketCap API

CoinMarketCap API is a data provider from CoinMarketCap providing crypto data. CoinMarketCap's commercial cryptocurrency data API provides live quotes, OHLCV candles, listings, market pairs, and metadata across thousands of coins and exchanges via a REST/JSON interface. A Polymarket bot uses it as a broad, authoritative cross-check reference price for "will BTC/ETH close above $X" markets and for settlement-dispute verification.
