## 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 coingecko-onchain-pool-ohlcv-a2be7f3c -d '<json body>'
```

Example prompt: Get me the last 100 hourly OHLCV candles for the Uniswap v3 pool at 0x88e6A0c2dDD26FEEb64F039a2c41296FcB3f5640 on Ethereum mainnet, priced in USD for the base token.

## When to prefer this

Use this endpoint when you need candlestick/OHLCV price history for a specific on-chain DEX liquidity pool by contract address, especially when you want flexible timeframe granularity (minute/hour/day) and currency denomination options. Prefer this over generic token price endpoints when working with pool-level data from GeckoTerminal-indexed networks.

## Known failure modes

- Invalid or unsupported network ID returns error or empty data
- Pool contract address not found on the specified network returns empty or error response
- Unsupported timeframe or aggregate value may return validation error
- before_timestamp in wrong format may cause query failure
- Exceeding API rate limits or payment failure returns 402 or rate limit error

## How this service works
