## 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 x402-free-hub-yield-best-pools-9df8c063 -d '<json body>'
```

Example prompt: Show me the top 5 yield pools on Ethereum with at least 8% APY so I can decide where to deploy my liquidity.

## When to prefer this

Use this endpoint when an agent needs to surface top DeFi yield opportunities on a specific blockchain, especially when the user wants to filter by a minimum APY threshold and control result count. Prefer this over generic DeFi dashboards when you need a structured, programmatic list of best pools ready for downstream decision-making.

## Known failure modes

- Unsupported or misspelled chain name returns empty results or an error
- minApy set too high returns no matching pools
- Data may be stale if underlying free data sources are not refreshed
- limit of 0 or negative may return an error or empty array
- Service may be unavailable if the Vercel deployment is down
