Endpoint
GEThttps://x402.asterpay.io/v1/market/ohlcv/bitcoin?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need structured OHLCV candlestick data for a specific cryptocurrency for charting, technical analysis, or trading algorithms. It is ideal for agents building price charts, computing indicators like RSI or MACD, or backtesting strategies, especially when you need a flexible symbol/interval/limit combination and are comfortable with micropayment-per-call pricing via x402.
