## 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 onchain-risk-agentdiet-dev-defi-stablecoin-liquidity-pool-yield-6486d9df
```

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

## When to prefer this

Choose this endpoint when you need a cross-chain, multi-protocol yield comparison for a specific asset in real time — especially for stablecoins (USDC, USDT) or major assets (ETH, WBTC, SOL) where yield arbitrage across Base, Arbitrum, Solana, and Ethereum is the goal. Prefer it over manual DeFiLlama queries when you need TVL-weighted, risk-adjusted ranking in a single API call.

## Known failure modes

- Unknown or unsupported asset symbol returns empty results or error
- DeFiLlama API downtime causes stale or missing APY data
- Low-liquidity assets may return few or no pools
- Rate limiting or payment failure (HTTP 402) if USDC micropayment not processed

## How this service works

## Output

Returns a structured list of DeFi liquidity pools for the requested asset, including live APY rates sourced from DeFiLlama, total value locked (TVL), risk-adjusted yield spreads, and pool metadata (protocol name, chain, pool address) ranked for yield arbitrage decision-making.
