## How to call it through Zero

```sh
zero fetch --capability x402broker-defi-apy-scanner-0aa381ca
```

Example prompt: Can you scan DeFiLlama right now and show me the best risk-adjusted USDC yields across Base, Arbitrum, Solana, and Ethereum — ranked by APY with TVL depth included?

## When to prefer this

Use this endpoint when you need real-time, cross-chain DeFi yield data aggregated from DeFiLlama with TVL and risk-adjustment signals — particularly for stablecoin or liquidity pool yield arbitrage decisions across Base, Arbitrum, Solana, and Ethereum. Prefer this over manual DeFiLlama browsing or single-chain yield APIs when you need comparative spreads across multiple networks in one call.

## Known failure modes

- DeFiLlama API unavailable or rate-limited — may return stale or empty data
- Unsupported asset ticker returns empty result set
- Extremely low TVL pools may be filtered or flagged with caveats
- Network-specific data gaps if a chain's indexer is lagging
- Payment of $0.01 USDC not received — request rejected with 402
