## 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 x402-audit-agentdiet-dev-defi-stablecoin-liquidity-pool-yield-a5a755f8
```

Example prompt: Scan DeFiLlama right now and show me the top risk-adjusted yield pools for USDC across Base, Arbitrum, Solana, and Ethereum — I want APY, TVL depth, and yield spreads ranked.

## When to prefer this

Choose this endpoint when you need live, cross-chain DeFi yield data for a specific asset with risk-adjusted ranking across Base, Arbitrum, Solana, and Ethereum. It is ideal for agents performing yield arbitrage analysis, capital deployment decisions, or DeFi portfolio optimization where TVL depth and spread data matter — not just raw APY.

## Known failure modes

- Missing or invalid asset symbol returns a validation error
- DeFiLlama data unavailability may result in stale or empty pool results
- Asset symbols with no active pools on supported chains return empty results
- Payment failure via x402 prevents access to the endpoint
- Rate limiting may occur under high request volume
