## 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-da062c0f
```

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

## When to prefer this

Choose this endpoint when you need live, cross-chain DeFi yield comparison for a specific asset across the major EVM and Solana ecosystems. It is ideal for yield arbitrage workflows, DeFi portfolio allocation decisions, or monitoring APY spreads without building your own DeFiLlama integration. Prefer it over raw DeFiLlama API access when you need risk-adjusted scoring and TVL depth in a single call.

## Known failure modes

- Unknown or unsupported asset symbol returns empty results or error
- DeFiLlama data temporarily unavailable causes stale or missing APY data
- Very new or low-liquidity assets may have insufficient pool data
- Payment failure via x402 returns HTTP 402 before data is served
- Rate limiting if too many requests are made in quick succession

## How this service works

## Output
