## 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 agentdiet-dev-defi-stablecoin-liquidity-pool-yield-arbitrage-scanner-fbbea5b0
```

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

## When to prefer this

Choose this endpoint when you need a cross-chain, multi-protocol DeFi yield comparison for a specific asset in real time, especially for stablecoins or major tokens like USDC, ETH, SOL, or WBTC. Prefer this over generic DeFi dashboards when you need risk-adjusted yield spreads and TVL depth aggregated from DeFiLlama across Base, Arbitrum, Solana, and Ethereum in a single call.

## Known failure modes

- Unknown or unsupported asset symbol returns no results or an error
- DeFiLlama upstream data unavailable causes stale or empty response
- Asset symbol with no active pools returns empty result set
- Malformed or missing asset parameter returns validation error
- Payment failure (402) if x402 micropayment not completed
