## 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-dc81f1c8
```

Example prompt: Scan all DeFi liquidity pools for USDC and show me the top risk-adjusted yields with TVL depth across Base, Arbitrum, Solana, and Ethereum — I want to know where I can get the best APY right now.

## When to prefer this

Choose this endpoint when you need live, multi-chain DeFi yield data aggregated from DeFiLlama with risk-adjusted scoring — particularly when comparing stablecoin or major asset yields across Base, Arbitrum, Solana, and Ethereum simultaneously. Prefer this over manual DeFiLlama browsing or single-chain yield tools when you need a ranked, risk-weighted view of pool opportunities in a single call.

## Known failure modes

- Missing or empty asset parameter returns validation error
- Unknown or unsupported asset symbol may return empty results or error
- DeFiLlama data unavailability causes stale or missing APY data
- Network latency or upstream API timeout from DeFiLlama
- Payment not processed (HTTP 402) if x402 micropayment fails
