## 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-db904c0f
```

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

## When to prefer this

Choose this endpoint when you need live, cross-chain DeFi yield data for a specific asset with risk-adjusted scoring and TVL context — particularly when comparing pools across Base, Arbitrum, Solana, and Ethereum simultaneously. Prefer this over generic DeFi dashboards when you need machine-readable, agent-consumable yield data for automated treasury management, yield arbitrage detection, or portfolio rebalancing decisions.

## Known failure modes

- Missing or empty 'asset' parameter returns a validation error
- Unknown or unsupported asset symbol may return empty pool results
- DeFiLlama data availability issues may result in stale or partial APY data
- Network timeouts if upstream DeFiLlama API is slow or unavailable
- Payment failure via x402 if USDC balance is insufficient
