## 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-4b91cbd5
```

Example prompt: Scan all the top DeFi liquidity pools for USDC and show me the best risk-adjusted APYs and TVL depth across Base, Arbitrum, Solana, and Ethereum right now.

## When to prefer this

Use this endpoint when you need live, cross-chain DeFi yield data for a specific asset and want risk-adjusted APY rankings alongside TVL depth — particularly useful for agents performing yield optimization, DeFi arbitrage scanning, or portfolio allocation decisions across Base, Arbitrum, Solana, and Ethereum. Prefer this over generic crypto price APIs when the goal is yield comparison rather than spot price lookup.

## Known failure modes

- Missing or empty 'asset' parameter returns a validation error
- Unsupported or unrecognized asset symbol may return empty results or an error
- DeFiLlama data unavailability may result in stale or missing pool data
- Rate limiting or payment failure (HTTP 402) if the $0.01 per-call fee is not settled
- Network timeouts if upstream DeFiLlama APIs are slow or unreachable
