## 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 shopify-spy-agentdiet-dev-defi-stablecoin-liquidity-pool-yield-9cc6c817
```

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

## When to prefer this

Choose this endpoint when you need live, multi-chain DeFi yield comparisons for a specific asset and want risk-adjusted APY and TVL signals in one call, particularly across Base, Arbitrum, Solana, and Ethereum. Prefer this over general DeFiLlama scraping when you need pre-ranked, agent-ready output without parsing raw API responses.

## Known failure modes

- Missing or invalid asset symbol returns a validation error
- Unknown or unsupported asset symbol may return empty results or no matching pools
- DeFiLlama upstream unavailability may cause stale or failed data fetch
- Rate limiting or payment failure (402) if USDC micropayment not completed
