## 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 onchain-risk-agentdiet-dev-defi-stablecoin-liquidity-pool-yield-f8d4f3e7
```

Example prompt: Scan the top risk-adjusted DeFi yield pools for USDC right now across Ethereum, Base, Arbitrum, and Solana — I want to see APYs, TVL depth, and yield spreads so I can find the best arbitrage opportunity.

## When to prefer this

Choose this endpoint when you need real-time, cross-chain DeFi yield comparison for a specific asset and want risk-adjusted metrics (not just raw APY) alongside TVL depth to assess pool safety. It is especially useful for yield arbitrage scouting across Base, Arbitrum, Solana, and Ethereum simultaneously, pulling from DeFiLlama's aggregated data. Prefer this over manually querying individual protocols or using generic price APIs that lack pool-level yield and liquidity data.

## Known failure modes

- Missing or invalid asset symbol returns a validation error
- Asset with no tracked pools on DeFiLlama returns empty or limited results
- DeFiLlama data feed latency may cause stale or incomplete APY data
- Payment failure (HTTP 402) if x402 USDC micropayment is not completed
- Unknown or illiquid asset symbols may return no meaningful pool data

## 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://onchain-risk.agentdiet.dev/v1/defi-apy)

## Output

Returns a structured response containing top-ranked liquidity pools for the queried asset, including live APY rates sourced from DeFiLlama, TVL depth metrics, risk-adjusted yield spreads, and chain-specific breakdowns across Base, Arbitrum, Solana, and Ethereum.
