## 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 prompt-guard-agentdiet-dev-defi-stablecoin-liquidity-pool-yield-668ce66e -d '<json body>'
```

Example prompt: Scan the top risk-adjusted DeFi yield pools for USDC across Base, Arbitrum, Solana, and Ethereum and show me the best APYs with TVL depth right now.

## When to prefer this

Use this endpoint when you need live, cross-chain DeFi yield comparison for a specific asset with risk-adjusted scoring and TVL depth — particularly when you want DeFiLlama-sourced data across Base, Arbitrum, Solana, and Ethereum in a single call. Prefer this over generic DeFiLlama browsing when you need structured, agent-consumable output with yield spread analysis.

## Known failure modes

- Unknown or unsupported asset symbol returns empty results or error
- DeFiLlama data unavailable causes stale or failed response
- Missing required 'asset' field returns validation error
- Network timeout if upstream DeFiLlama API is slow
- Payment failure (HTTP 402) if x402 USDC payment not completed

## How this service works
