## 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 agent-data-bench-dex-pool-ohlcv-candles-61facb69
```

Example prompt: Can you pull the last 200 hourly OHLCV candles for the Solana pool at address 7XawhbbxtsRcQA8KTkHT9f9nc6d69UwqCDh6U5EEbEmX so I can calculate RSI?

## When to prefer this

Choose this endpoint when you need raw OHLCV candlestick data for a specific DEX pool on Solana, Ethereum, or Base without operating your own indexer or decoding swap events. It is ideal for backtesting, computing technical indicators (RSI, MACD, Bollinger Bands), or rendering price charts. It supports fine-grained intervals down to 1 second and returns data in a clean numeric format ready for quantitative use. Prefer it over general market data APIs when you need DEX-specific pool-level granularity rather than centralized exchange data.

## Known failure modes

- Invalid or unrecognized pool address returns an error or empty result
- Unsupported chain identifier returns a validation error
- Requested interval not in the supported enum returns a 400-level error
- End time in the future or far past may return fewer candles than requested
- Outlier prints included when outlier flag is false by default, unexpected price spikes may appear
- Payment failure (x402 protocol) blocks the response entirely
- Rate limiting or network timeouts on the provider side

## How this service works

OHLCV candles for any DEX pool, from 1 second to 1 day buckets, newest N returned oldest-first with numeric open/high/low/close/volume. Drop-in for backtests, indicator calculations and chart rendering without running an indexer or decoding swap events.

## Output

An ordered array of OHLCV candle objects (oldest first), each containing numeric open, high, low, close, and volume fields plus a timestamp, for the requested pool, chain, interval, and time window. Up to 500 candles returned per call.
