## 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-on-chain-pool-data-abede52e -d '<json body>'
```

Example prompt: Can you pull up the current price, volume, and transaction data for the Uniswap ETH/USDC pool at contract address 0x88e6A0c2dDD26FEEb64F039a2c41296FcB3f5640 on the eth network?

## When to prefer this

Use this endpoint when you need real-time on-chain pool metrics (price, volume, transactions) for a specific liquidity pool identified by its contract address on a supported EVM-compatible network. Prefer this over token price endpoints when you need pool-level granularity rather than token-level aggregates, or when you want DEX-specific data tied to a particular pool contract.

## Known failure modes

- Invalid or unrecognized pool contract address returns an empty or error response
- Unsupported network ID causes a lookup failure
- Pool contract exists on-chain but is not indexed by CoinGecko/GeckoTerminal
- Missing required fields (network or address) results in a validation error
- Network congestion or provider downtime causes timeout

## How this service works

Pay-per-request access to CoinGecko, DefiLlama, Alchemy, and Etherscan APIs. No auth, no subscriptions.

## Output

Returns a data object containing pool-level details such as current token price, recent transaction counts, trading volume figures, and other pool metrics sourced from GeckoTerminal's on-chain data for the specified contract address and network.
