## 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-category-pools-6e0242d1 -d '<json body>'
```

Example prompt: Pull the first page of on-chain liquidity pools in the 'decentralized-exchange' category from CoinGecko, sorted by volume, and include base token info.

## When to prefer this

Use this endpoint when you need to enumerate or browse liquidity pools scoped to a specific on-chain DeFi category (e.g. stablecoins, liquid staking, DEXes) rather than scanning all pools or searching by network. Ideal when the user wants to compare pools within a themed category or build a category-specific pool leaderboard.

## Known failure modes

- Missing or invalid category_id returns an error or empty data array
- Unknown category_id returns empty results
- Invalid sort or include parameter may return an error or be ignored
- Pagination beyond available pages returns empty data
- Rate limiting or payment failure returns a 402 or 429 error
