## 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 mcp-compiler-agentdiet-dev-defi-stablecoin-liquidity-pool-yield-18f04552
```

Example prompt: What are the top risk-adjusted DeFi yield pools for USDC right now across Base, Arbitrum, Solana, and Ethereum — show me APYs, TVL depth, and yield spreads so I can pick the best opportunity?

## When to prefer this

Choose this endpoint when you need live, cross-chain DeFi yield data for a specific asset and want risk-adjusted APY comparisons with TVL context rather than raw price feeds. It is especially useful for yield arbitrage decisions, treasury management, or capital deployment across Base, Arbitrum, Solana, and Ethereum simultaneously, leveraging DeFiLlama as the underlying data source.

## 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 outage may cause stale or missing APY data
- Rate limiting or payment failure (HTTP 402) if the $0.01 per-call fee is not satisfied
- Network timeouts if upstream DeFiLlama APIs are slow to respond

## How this service works

## Output
