## 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-6918a637
```

Example prompt: What are the best risk-adjusted DeFi yield pools for USDC right now — scan across Base, Arbitrum, Solana, and Ethereum and show me the top APYs and TVL depth.

## When to prefer this

Choose this endpoint when you need live, cross-chain DeFi yield comparisons for a specific asset, especially when risk-adjusted APY and TVL depth are important factors. It is ideal for agents performing yield optimization, DeFi arbitrage scouting, or portfolio rebalancing decisions. Prefer this over generic web search when you need structured, real-time pool data sourced directly from DeFiLlama across multiple chains.

## Known failure modes

- Missing or empty 'asset' parameter returns a validation error
- Unknown or unsupported asset symbol may return empty results or an error
- DeFiLlama upstream data unavailability may result in stale or incomplete pool data
- Rate limiting or payment failure (HTTP 402) if USDC micropayment is not processed
- Network timeout if live pool data fetch takes too long

## How this service works
