## 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 fiatdock-defi-yields-best-apy-across-lending-staking-pools-04b12b31
```

Example prompt: What's the best APY I can get for USDC right now across DeFi lending and staking pools? Show me the top 5 results on Ethereum with at least $5M TVL and exclude outliers.

## When to prefer this

Choose this endpoint when you need a real-time, cross-protocol comparison of DeFi yields (APY) across lending and staking pools, especially when you want to filter by asset, chain, TVL, or project. Prefer this over manual protocol checks or aggregator UIs when you need programmatic, up-to-date yield data for decision-making or portfolio optimization in an automated agent workflow.

## Known failure modes

- No pools found matching the specified asset or chain — returns empty results
- minTvlUsd set too high may filter out all pools — returns empty list
- Invalid asset or chain names may return empty results or an error
- Service may return stale APY data if underlying protocol data is delayed
- includeOutliers=false may remove legitimately high-yield pools along with suspicious ones

## How this service works

Pay-per-call: true402 DeFi Yields — best APY across lending & staking pools

## Output

Returns a ranked list of DeFi pools with current APY rates, including the protocol/project name, asset, chain, TVL in USD, and yield type (lending vs staking), filtered and sorted according to query parameters.
