CoinDCX
CoinDCX is India's largest cryptocurrency exchange, providing REST and WebSocket APIs spanning spot, margin, and lending markets. Market data endpoints — tickers, order books, and candles across 13 intervals — are public and keyless, while trading, balances, and transfers require HMAC-SHA256-signed requests with an API key and secret. The API is free to use, with per-endpoint rate limits ranging from 30 to 2,000 requests per 60-second window.
