Crypto Historical Price & Market Data

Use this endpoint when you need time-series historical data (price, market cap, volume) for a specific cryptocurrency — ideal for charting, backtesting, trend analysis, or answering questions about past crypto performance. Prefer this over real-time price endpoints when the user needs data spanning days, weeks, or months rather than the current spot price.

• Unknown or unsupported coin symbol returns an error or empty result
• Invalid date range parameters return a 400 error
• Payment of 0.003 USDC not fulfilled triggers 402 Payment Required
• Rate limiting or server overload returns 429 or 503
• Very recently listed coins may have incomplete historical data
