## 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-920b0ead
```

Example prompt: Can you scan all the top DeFi pools for USDC right now and show me the best risk-adjusted yields across Base, Arbitrum, Solana, and Ethereum — including APY and TVL depth?

## When to prefer this

Prefer this endpoint when you need live, multi-chain DeFi yield data for a specific asset and want risk-adjusted comparisons across major EVM chains and Solana simultaneously. It is especially useful for yield arbitrage workflows, treasury management agents, or DeFi portfolio optimization bots that need real TVL and APY data rather than static or aggregated snapshots. Choose this over generic crypto price APIs when yield farming pool intelligence — not spot price — is the goal.

## Known failure modes

- Missing or invalid asset symbol returns a validation error
- Unknown or unsupported asset symbols may return empty results if not tracked by DeFiLlama
- DeFiLlama data latency may cause slightly stale APYs during high-volatility periods
- Payment failure (x402) blocks the request if USDC balance is insufficient
- Network timeout if DeFiLlama upstream is slow or unavailable

## 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/apy-radar)

## Output

Returns a structured list of DeFi liquidity pools for the requested asset, including live APY rates sourced from DeFiLlama, TVL (total value locked) depth per pool, risk-adjusted yield spreads, and pool/protocol breakdowns across Base, Arbitrum, Solana, and Ethereum networks.
