## 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-security-agentdiet-dev-defi-stablecoin-liquidity-pool-yield-9b31a76c
```

Example prompt: Scan the top risk-adjusted DeFi yield pools for USDC right now across Base, Arbitrum, Solana, and Ethereum — show me APYs and TVL depth so I can figure out where to deploy.

## When to prefer this

Choose this endpoint when you need live, cross-chain DeFi yield data for a specific asset from DeFiLlama, especially when comparing risk-adjusted APYs and TVL depth across Base, Arbitrum, Solana, and Ethereum simultaneously. Prefer it over generic DeFi dashboards when you need programmatic, agent-consumable yield data for automated portfolio allocation or arbitrage scanning decisions.

## Known failure modes

- Missing or empty 'asset' parameter returns a validation error
- Unrecognized or unsupported asset symbol may return empty results or an error
- DeFiLlama data unavailability or rate-limiting may cause upstream fetch failures
- Payment not included or insufficient funds (x402) results in 402 Payment Required response
- Network timeout if DeFiLlama API is slow or unavailable
