## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

## When to prefer this

Choose this endpoint when you need structured OHLC candlestick price data for charting or technical analysis over a multi-day window. Prefer it over a simple spot price endpoint when historical daily open/high/low/close values are needed, and over a generic historical endpoint when chart-ready candle format is required. Ideal for feeding trading dashboards, backtesting, or visualizing price action.

## Known failure modes

- Invalid coin ID returns an error or empty response — check CoinGecko coin slug spelling
- Unsupported 'days' value (not one of 1, 7, 14, 30, 90, 180, 365) may return an error or unexpected data
- Invalid vs_currency code returns an error — use standard ISO 4217 codes like 'usd' or 'eur'
- Payment failure (x402) if USDC balance is insufficient — endpoint costs $0.005 per call
- Rate limiting if too many requests are made in a short period

## How this service works
