Technical details
Endpoint
GEThttps://api.xynaptic.io/v1/crypto-historical?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need daily OHLCV candlestick history for a specific cryptocurrency over a fixed window of 30, 90, or 365 days, especially for backtesting trading strategies or analyzing historical price behavior. It is best suited for structured quantitative analysis where timestamped open/high/low/close arrays are required. Prefer it over live price endpoints when historical context is needed rather than real-time quotes.
Side effects
- Unsupported coin ID returns an error or empty result
- Days parameter outside allowed values (30, 90, 365) may return an error
- Rate limiting or payment failure results in 402 or 429 response
- CoinGecko data unavailable or delayed causes stale or missing candles
- Malformed query parameters (e.g. missing 'coin') return a 400 bad request
