## 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-499ea9e2
```

Example prompt: What are the top risk-adjusted DeFi yield pools for USDC right now across Base, Arbitrum, Solana, and Ethereum — show me APY and TVL depth so I can decide where to deploy?

## When to prefer this

Choose this endpoint when you need live, cross-chain DeFi yield data for a specific asset and want risk-adjusted comparisons rather than raw APY alone. It is ideal for agents performing yield optimization, treasury deployment decisions, or DeFi arbitrage scanning across Base, Arbitrum, Solana, and Ethereum simultaneously. Prefer over manual DeFiLlama queries when you need structured, agent-ready output with TVL context in a single call.

## Known failure modes

- Invalid or unrecognized asset symbol returns empty or error response
- DeFiLlama data unavailability causes stale or missing pool data
- Asset has no pools on supported chains resulting in empty result set
- Rate limiting or payment failure (HTTP 402) if payment not properly handled
- Network timeout for real-time pool data fetching
