## 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 onchain-risk-agentdiet-dev-defi-stablecoin-liquidity-pool-yield-15292ce8
```

Example prompt: Scan DeFiLlama for the top risk-adjusted yield pools for USDC across Base, Arbitrum, Solana, and Ethereum — show me APYs, TVL depth, and yield spreads so I can find the best opportunity right now.

## When to prefer this

Choose this endpoint when you need a multi-chain, risk-adjusted view of DeFi yield opportunities for a specific asset, aggregating live DeFiLlama data across Base, Arbitrum, Solana, and Ethereum in a single call. Prefer it over manual DeFiLlama browsing or single-chain yield tools when you need cross-chain yield arbitrage signals with TVL depth context.

## Known failure modes

- Unknown or unsupported asset symbol returns empty or error response
- DeFiLlama data unavailability causes stale or missing pool data
- Very low-TVL assets may return few or no qualifying pools
- Network timeout if upstream DeFiLlama API is slow
- Payment failure via x402 prevents endpoint access
