## 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-data-hub-v2-best-yield-pools-adeb5162 -d '<json body>'
```

Example prompt: What are the best yield pools available on Base right now? Only show me stablecoin pools — I want the highest APY options.

## When to prefer this

Use this endpoint when you need real-time DeFi yield pool rankings filtered by chain (e.g. Ethereum, Base) or stablecoin status; ideal for agents helping users find passive income opportunities in DeFi without manually searching multiple protocols

## Known failure modes

- Invalid or unsupported chain name returns an error or empty result
- Payment failure (402) if x402 USDC payment is not included or insufficient
- No pools match filter combination (e.g. no stablecoin pools indexed for a niche chain)
- Upstream data source unavailable causing stale or missing pool data
