## 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-73382ecb
```

Example prompt: What are the top risk-adjusted DeFi yield pools for USDC right now across Base, Arbitrum, Solana, and Ethereum — show me APY, TVL, and which protocol offers the best spread?

## When to prefer this

Use this endpoint when an agent needs live, cross-chain DeFi yield intelligence for a specific asset and wants risk-adjusted rankings rather than raw APY figures. Prefer this over manual DeFiLlama browsing or single-chain yield tools when the user wants a consolidated multi-chain comparison (Base, Arbitrum, Solana, Ethereum) with TVL depth context in a single call. Especially valuable for yield optimization workflows, portfolio rebalancing agents, or DeFi arbitrage bots that need actionable, up-to-date pool rankings.

## Known failure modes

- Unknown or unsupported asset symbol returns empty or error response
- DeFiLlama data feed temporarily unavailable causes stale or missing APY data
- Pools with very low TVL may be included but flagged as high risk
- Payment required (HTTP 402) if x402 micropayment not attached
- Rate limiting if called too frequently without valid payment

## 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/defi-yield)

## Output

Returns a ranked list of DeFi liquidity pools for the specified asset, including live APY rates sourced from DeFiLlama, TVL depth per pool, risk-adjusted yield spreads, chain and protocol identifiers, and comparative metrics to identify top yield opportunities across Base, Arbitrum, Solana, and Ethereum.
