## 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 shopify-spy-agentdiet-dev-defi-stablecoin-liquidity-pool-yield-ab998d06
```

Example prompt: Scan live DeFi yield pools for USDC and show me the top risk-adjusted APY opportunities across Base, Arbitrum, Solana, and Ethereum right now.

## When to prefer this

Choose this endpoint when you need a cross-chain, multi-protocol DeFi yield scan for a specific asset — particularly for stablecoins or major tokens like ETH, SOL, or WBTC. It aggregates DeFiLlama APY and TVL data in a single call with risk-adjusted ranking, making it ideal for yield arbitrage decisions across Base, Arbitrum, Solana, and Ethereum rather than checking each protocol manually.

## Known failure modes

- Missing or invalid asset symbol returns an error
- Unknown or unsupported asset symbol may return empty results
- DeFiLlama data unavailable or rate-limited may cause partial or failed response
- Network timeout if upstream data sources are slow

## How this service works

## Output

Returns a ranked list of DeFi liquidity pools for the requested asset, including APY rates sourced from DeFiLlama, TVL depth, chain (Base, Arbitrum, Solana, Ethereum), protocol name, and risk-adjusted yield spread data to help identify optimal yield opportunities.
