## 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 whale-momentum-agentdiet-dev-defi-stablecoin-liquidity-pool-yield-30c80efa
```

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

## When to prefer this

Use this endpoint when you need live, cross-chain DeFi yield data for a specific asset and want risk-adjusted APY comparisons across major chains (Base, Arbitrum, Solana, Ethereum) without manually querying DeFiLlama. Prefer this over generic DeFi dashboards when you need machine-readable, agent-consumable yield rankings in a single call.

## Known failure modes

- Unknown or unsupported asset symbol returns empty or error response
- DeFiLlama upstream data unavailability may cause stale or missing results
- Very low-liquidity assets may return few or no matching pools
- Rate limiting or payment failures (HTTP 402) if $0.01 USDC micro-payment is not settled
- Malformed asset parameter (e.g. empty string) returns validation error
