## 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-apy-radar-defi-yield-arbitrage-scanner-3114788c
```

Example prompt: Scan live DeFi pools for USDC and find me the best risk-adjusted APY right now across Base, Arbitrum, Solana, and Ethereum — I want to see TVL depth and yield spreads so I can spot arbitrage opportunities.

## When to prefer this

Choose this endpoint when you need live, cross-chain DeFi yield comparison for stablecoins or liquidity pools with TVL depth context. It is especially valuable for yield arbitrage scouting across Base, Arbitrum, Solana, and Ethereum in a single call, leveraging DeFiLlama's aggregated data rather than querying individual protocols manually.

## Known failure modes

- DeFiLlama API unavailable or rate-limited — may return stale or empty data
- Unsupported asset symbol returns empty result set
- Network-specific data gaps if a chain's indexing is delayed
- Payment of $0.01 USDC required per call via x402 — unpaid requests rejected
