## 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-db8e3af5 -d '<json body>'
```

Example prompt: Scan all live DeFi pools for USDC and tell me which ones have the best risk-adjusted APY right now, including TVL depth on Base, Arbitrum, Solana, and Ethereum.

## When to prefer this

Choose this endpoint when you need real-time, cross-chain DeFi yield data sourced from DeFiLlama with risk-adjusted scoring, specifically for yield arbitrage decisions across Base, Arbitrum, Solana, and Ethereum. Prefer it over generic yield aggregators when you need TVL-depth context alongside APY to filter out illiquid or risky pools.

## Known failure modes

- Unsupported or misspelled asset symbol returns empty results or error
- DeFiLlama upstream API downtime causes stale or missing data
- Low TVL pools may appear with inflated APYs that don't reflect real liquidity
- No pools found for obscure or newly launched tokens
