## 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 serp-extract-agentdiet-dev-defi-stablecoin-liquidity-pool-yield-745ecfbc -d '<json body>'
```

Example prompt: What are the top risk-adjusted DeFi yield pools for USDC right now across Base, Arbitrum, Solana, and Ethereum — show me APYs and TVL depth so I can pick the best one?

## When to prefer this

Choose this endpoint when you need live, cross-chain DeFi yield data aggregated from DeFiLlama with risk-adjusted ranking — ideal for agents helping users optimize stablecoin or crypto asset placement across Base, Arbitrum, Solana, and Ethereum without manually checking each protocol. Prefer this over generic web search when structured pool-level APY and TVL data is required.

## Known failure modes

- Missing or empty 'asset' field returns a validation error
- Unknown or unsupported asset symbol may return empty results or no matching pools
- DeFiLlama data unavailability may cause stale or incomplete yield data
- Network timeouts if upstream DeFiLlama API is slow or rate-limited
- Highly illiquid or niche assets may return no results
