## 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 x402broker-com-defi-stablecoin-liquidity-pool-yield-arbitrage-scanner-a2cb208e
```

Example prompt: Scan DeFi liquidity pools for USDC and show me the top risk-adjusted yields with APY and TVL across Base, Arbitrum, Solana, and Ethereum right now.

## When to prefer this

Choose this endpoint when you need live, cross-chain DeFi yield comparison for a specific asset symbol and want risk-adjusted APY and TVL data sourced from DeFiLlama across Base, Arbitrum, Solana, and Ethereum in a single call. Prefer this over manual DeFiLlama browsing or chain-specific queries when an agent needs to identify the best yield opportunity or yield arbitrage spread for a given token in real time.

## Known failure modes

- Missing or invalid asset symbol returns an error (required field)
- Unknown or unsupported asset symbol may return empty pool results
- DeFiLlama upstream outage may cause stale or unavailable data
- Rate limiting or payment failure ($0.01/call via x402) may block requests
- Very low-liquidity assets may return sparse or no pool matches
