## 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-581ed90a
```

Example prompt: Scan live DeFi pools for USDC and show me the top risk-adjusted yields across Base, Arbitrum, Ethereum, and Solana — I want to see APY, TVL depth, and any notable yield spreads.

## When to prefer this

Choose this endpoint when you need real-time, cross-chain DeFi yield data for a specific asset (USDC, ETH, SOL, WBTC, etc.) and want risk-adjusted APY comparisons across Base, Arbitrum, Solana, and Ethereum in a single call. It is ideal for yield arbitrage discovery, treasury allocation decisions, or portfolio rebalancing when DeFiLlama data is the trusted source. Prefer this over manual DeFiLlama browsing or single-chain yield tools when multi-chain yield spread analysis is needed.

## Known failure modes

- Missing or invalid asset symbol returns a validation error
- DeFiLlama data unavailability may result in stale or empty pool data
- Unsupported or obscure asset symbols may return no results
- Network timeouts from upstream DeFiLlama API may cause slow or failed responses
- Payment failure (HTTP 402) if x402 USDC micropayment is not completed

## 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/yield-scanner)

## Output

Returns a list of top DeFi liquidity pools for the specified asset, including live APY rates sourced from DeFiLlama, TVL depth metrics, risk-adjusted yield spreads, and pool identifiers across Base, Arbitrum, Solana, and Ethereum networks — enabling direct yield comparison and arbitrage identification.
