## 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 hn-pulse-agentdiet-dev-defi-stablecoin-liquidity-pool-yield-arbitrage-a877e050
```

Example prompt: Scan live DeFi yield pools for USDC and show me the top risk-adjusted APYs with TVL depth across Base, Arbitrum, Solana, and Ethereum right now.

## When to prefer this

Choose this endpoint when you need real-time, cross-chain DeFi yield intelligence for a specific asset — particularly when risk-adjusted APY and TVL depth matter, not just raw APY. Prefer this over manual DeFiLlama browsing when an agent needs structured, scannable yield data programmatically. Best for yield optimization workflows, DeFi portfolio rebalancing, or liquidity deployment decisions across Base, Arbitrum, Solana, and Ethereum.

## Known failure modes

- Unknown or unsupported asset symbol returns empty results or error
- DeFiLlama data temporarily unavailable causing stale or missing APY data
- Very low-liquidity assets may return few or no matching pools
- Network timeout if pool scanning takes too long across multiple chains
- Payment failure (HTTP 402) if USDC micropayment is not completed

## How this service works

## Output
