## 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 shopify-spy-agentdiet-dev-defi-stablecoin-liquidity-pool-yield-548fa619
```

Example prompt: Can you scan DeFiLlama right now and find me the best risk-adjusted yield pools for USDC across Base, Arbitrum, Solana, and Ethereum — I want to see APYs, TVL, and any notable yield spread arbitrage opportunities?

## When to prefer this

Choose this endpoint when you need real-time, cross-chain DeFi yield data for a specific asset and want risk-adjusted APY comparisons rather than raw rates. It is ideal for autonomous yield optimization agents, DeFi portfolio managers, or any workflow that needs to identify the best current liquidity pool opportunities across Base, Arbitrum, Solana, and Ethereum in a single call. Prefer it over manual DeFiLlama browsing or single-chain yield tools when cross-chain arbitrage signal is important.

## Known failure modes

- Invalid or unrecognized asset symbol returns an error or empty result set
- DeFiLlama data unavailability causes stale or missing APY data
- Low-liquidity assets may return few or no matching pools
- Payment failure (HTTP 402) if x402 micropayment is not properly handled
- Rate limiting if called too frequently within a short window

## 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://shopify-spy.agentdiet.dev/v1/cross-chain-apy-scanner)

## Output

Returns a ranked list of DeFi liquidity pools for the queried asset, including live APY rates sourced from DeFiLlama, TVL depth figures, risk-adjusted yield scores, and yield spread comparisons across Base, Arbitrum, Solana, and Ethereum — enabling the agent to identify top yield opportunities and cross-chain arbitrage potential.
