## 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-6cdbe46b
```

Example prompt: Scan DeFiLlama for the best risk-adjusted APY pools for USDC across Base, Arbitrum, Solana, and Ethereum — I want to know where I can get the highest yield with solid TVL depth.

## When to prefer this

Choose this endpoint when you need live, cross-chain DeFi yield data aggregated from DeFiLlama for a specific asset, especially when comparing APY and TVL depth across Base, Arbitrum, Solana, and Ethereum simultaneously for risk-adjusted yield arbitrage decisions. Prefer this over manual DeFiLlama browsing or single-chain APY queries when you need a structured, agent-ready response covering multiple chains at once.

## Known failure modes

- Missing required 'asset' parameter returns validation error
- Unknown or unsupported asset symbol may return empty results or error
- DeFiLlama API downtime may cause stale or unavailable data
- Rate limiting or payment failure (HTTP 402) if payment not processed
- Network timeout if cross-chain data aggregation is slow

## How this service works

Scans live DeFiLlama APYs, TVL depth, and risk-adjusted yield spreads across Base, Arbitrum, Solana, and Ethereum pools. (Live x402 v2, IETF MPP & MCP endpoint at https://mcp-security.agentdiet.dev/v1/cross-chain-apy-scanner)

## Output

Returns live APY rates, TVL depth metrics, and risk-adjusted yield spread data for the queried asset across DeFi liquidity pools on Base, Arbitrum, Solana, and Ethereum, ranked or filtered for yield arbitrage opportunities.
