## 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-eab7d181 -d '<json body>'
```

Example prompt: Scan DeFiLlama for the best risk-adjusted USDC liquidity pool yields across Base, Arbitrum, Solana, and Ethereum right now — show me the top pools ranked by APY and TVL depth.

## When to prefer this

Choose this endpoint when you need live, multi-chain DeFi yield data for a specific asset and want risk-adjusted APY comparisons across liquidity pools in a single call. Prefer it over manually querying DeFiLlama or chain-specific dashboards when an agent needs to programmatically rank yield opportunities across Base, Arbitrum, Solana, and Ethereum simultaneously.

## Known failure modes

- Unknown or unsupported asset symbol returns an error or empty results
- DeFiLlama API unavailability causes stale or missing APY data
- Assets with very low liquidity may return few or no pools
- Rate limiting or payment failure (HTTP 402) if USDC micropayment is not processed
- Malformed asset symbol (e.g. typo) results in no match
