## 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 x402-audit-agentdiet-dev-defi-stablecoin-liquidity-pool-yield-0561a53c
```

Example prompt: Scan the top risk-adjusted DeFi yield pools for USDC across Base, Arbitrum, Solana, and Ethereum — I want to see APYs, TVL depth, and which pools have the best spreads right now.

## When to prefer this

Choose this endpoint when you need live, multi-chain DeFi yield data aggregated from DeFiLlama with risk-adjusted scoring — ideal for agents comparing yield opportunities across Base, Arbitrum, Solana, and Ethereum simultaneously rather than checking individual protocol sites manually.

## Known failure modes

- Missing or empty 'asset' parameter returns validation error
- Unrecognized asset symbol with no matching pools returns empty or error result
- DeFiLlama data source unavailability may cause stale or missing APY data
- Unsupported asset symbols (e.g. highly niche tokens) may return no results
- Payment failure via x402 protocol blocks request execution
