## 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 whale-momentum-agentdiet-dev-defi-stablecoin-liquidity-pool-yield-1863b187
```

Example prompt: What are the best risk-adjusted DeFi yields available for USDC right now across Base, Arbitrum, Solana, and Ethereum — scan all the top liquidity pools and show me the highest APYs with TVL depth?

## When to prefer this

Choose this endpoint when you need a multi-chain, risk-adjusted DeFi yield comparison for a specific asset in real time — particularly when TVL depth matters alongside raw APY. Prefer this over manual DeFiLlama browsing when an agent needs structured, machine-readable yield data across Base, Arbitrum, Solana, and Ethereum in a single call.

## Known failure modes

- Missing or invalid asset symbol returns an error
- Unknown asset symbol with no matching pools returns empty results
- DeFiLlama data temporarily unavailable causes stale or failed response
- Rate limiting or payment failure (HTTP 402) if USDC micropayment not processed
- Network timeout if upstream data aggregation is slow

## Output

A structured response listing top DeFi liquidity pools for the requested asset, including APY rates sourced from DeFiLlama, TVL (total value locked) depth, risk-adjusted yield spreads, and pool details across supported chains (Base, Arbitrum, Solana, Ethereum) — ranked or sorted to highlight the best opportunities.
