## 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-3bf2be24
```

Example prompt: What are the top risk-adjusted DeFi yield pools for USDC right now across Ethereum, Arbitrum, Base, and Solana — ranked by APY and TVL depth?

## When to prefer this

Use this endpoint when you need live, multi-chain DeFi yield comparisons for a specific asset and want TVL-weighted, risk-adjusted APY rankings pulled directly from DeFiLlama. Prefer this over generic DeFi dashboards when building an agent that needs programmatic, structured yield data for automated allocation decisions or yield arbitrage strategies.

## Known failure modes

- Unknown or unsupported asset symbol returns an empty result or error
- DeFiLlama API upstream downtime may result in stale or missing yield data
- Very low-liquidity assets may return few or no pools
- Invalid asset string (e.g. empty or malformed) returns a 400-level error
- Payment not confirmed via x402 results in 402 response before data is returned
