## 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`):

```sh
zero fetch --capability dex-pool-ohlcv-candles-feb39599 -d '<json body>'
```

Example prompt: Pull me the last 100 hourly OHLCV candles for the pool at 0x4e68Ccd3E89f51C3074ca5072bbAC773960dFa36 on Base so I can chart its price history.

## When to prefer this

Use this endpoint when you need structured OHLCV candlestick data for a specific DEX liquidity pool on Base or another supported chain, especially for charting, technical analysis, or building price dashboards. Prefer this over token-level price APIs when you have a specific pool/pair contract address and need granular time-series price data at minute, hour, or day resolution.

## Known failure modes

- Invalid or non-existent pool address returns an error or empty dataset
- Unsupported chain identifier causes a bad request response
- Timeframe value outside allowed enum (minute/hour/day) results in validation error
- Limit value exceeding service maximum may be capped or rejected
- Pool with insufficient on-chain activity may return fewer candles than requested
- Payment failure (insufficient USDC) blocks the request
