## 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 json-repair-agentdiet-dev-defi-stablecoin-liquidity-pool-yield-d5c7af10
```

Example prompt: What are the top risk-adjusted DeFi yield pools for USDC right now across Base, Arbitrum, Solana, and Ethereum — show me APYs and TVL depth so I can find the best place to park my stablecoins?

## When to prefer this

Choose this endpoint when you need live, cross-chain DeFi yield comparisons for a specific asset and want risk-adjusted metrics rather than raw APY alone. It is especially useful for stablecoin yield arbitrage, portfolio reallocation decisions, or monitoring yield spreads across Aave v3 and other major protocols on Base, Arbitrum, Solana, and Ethereum simultaneously.

## Known failure modes

- Unknown or unsupported asset symbol returns empty results or error
- DeFiLlama data temporarily unavailable causes stale or missing APY data
- Network-specific pools may be absent if chain indexing is lagging
- Rate limiting or payment failure (HTTP 402) if USDC micropayment not fulfilled
- Malformed asset symbol (e.g. lowercase or typo) may return no matching pools
