## 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-fce2fb87
```

Example prompt: What are the top risk-adjusted DeFi yield pools for USDC right now across Base, Arbitrum, Solana, and Ethereum — show me APYs, TVL depth, and any notable yield spreads I could arbitrage?

## When to prefer this

Choose this endpoint when you need live, cross-chain DeFi yield data for a specific asset and want risk-adjusted APY comparisons across multiple networks (Base, Arbitrum, Solana, Ethereum) in a single call. Prefer this over manually querying DeFiLlama when you need structured, agent-ready output for yield arbitrage or capital allocation decisions.

## Known failure modes

- Missing or invalid asset symbol returns an error
- Unsupported asset symbols (not listed on DeFiLlama) return empty or error responses
- DeFiLlama data latency or outage may result in stale or unavailable yield data
- Rate limiting or payment failure (x402) blocks the request
- Network timeouts if downstream DeFiLlama API is slow
