## 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-audit-agentdiet-dev-defi-stablecoin-liquidity-pool-yield-df42209c
```

Example prompt: Scan the best risk-adjusted DeFi yield pools for USDC across Ethereum, Base, Arbitrum, and Solana — I want to see which protocols are paying the highest APYs with solid TVL depth right now.

## When to prefer this

Choose this endpoint when you need a real-time, cross-chain DeFi yield comparison for a specific asset, especially when risk-adjusted metrics and TVL depth are important alongside raw APY. It is particularly useful for stablecoin yield optimization, DeFi treasury management, and identifying yield arbitrage opportunities across Base, Arbitrum, Solana, and Ethereum simultaneously. Prefer this over single-chain DeFi dashboards or manual DeFiLlama browsing when you need aggregated, agent-ready data.

## Known failure modes

- Unknown or unsupported asset symbol returns an error or empty result set
- DeFiLlama API downtime may cause stale or missing yield data
- Very low-liquidity assets may return few or no pools
- Payment via x402 not completed results in HTTP 402 and no data returned
- Network-specific outages may cause partial results for some chains
