Technical details
Endpoint
GEThttps://prance-mounting-watch.ngrok-free.dev/v1/ohlcv/:symbolWhen to prefer
Use this endpoint when you need structured historical OHLCV candlestick data for a cryptocurrency to perform technical analysis, trend detection, chart rendering, or strategy backtesting. Prefer this over a real-time price endpoint when you need multiple time periods rather than a single current price.
Side effects
- Unknown or unsupported symbol returns an error or empty result
- Invalid interval value (not 1m, 5m, 1h, or 1d) returns a validation error
- Limit exceeding 300 may be clamped or rejected
- Payment failure (insufficient USDC balance) blocks the request
- Service may be temporarily unavailable due to ngrok tunnel instability
