## 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-dff5735a
```

Example prompt: Scan the top risk-adjusted DeFi yield pools for USDC across Base, Arbitrum, Solana, and Ethereum and show me the best APYs with TVL depth right now.

## When to prefer this

Choose this endpoint when you need live, cross-chain DeFi yield data sourced from DeFiLlama for a specific asset, especially when comparing risk-adjusted APYs and TVL across multiple chains (Base, Arbitrum, Solana, Ethereum) simultaneously. Prefer this over manual DeFiLlama browsing or single-chain yield tools when you need arbitrage-ready spread analysis in a single API call.

## Known failure modes

- Invalid or unsupported asset symbol returns an error or empty results
- DeFiLlama API downtime may cause stale or missing APY data
- Very low-liquidity assets may return few or no pools
- Rate limiting or payment failure via x402 protocol may block the request
