## 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-search-485ca8c9 -d '<json body>'
```

Example prompt: Search CoinGecko on-chain pools for 'USDC-ETH' on the Ethereum network and show me the first page of results.

## When to prefer this

Use this endpoint when you need to search for on-chain liquidity pools by name, token symbol, or pair keyword — especially when you want to filter by blockchain network. Prefer this over trending or price endpoints when the user wants to discover specific pools rather than browse trending assets or look up prices by contract address.

## Known failure modes

- Missing required 'query' field returns a validation error
- Invalid or unsupported network name may return empty results
- No pools found for obscure or misspelled query returns empty data array
- Rate limiting or payment failure returns a 402 or 429 error
- Pagination with out-of-range page number may return empty results

## How this service works

## Output
