## 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-6a96a9d8
```

Example prompt: Scan live DeFi liquidity pools for USDC and show me the top risk-adjusted APY opportunities across Base, Arbitrum, Solana, and Ethereum, including TVL depth.

## When to prefer this

Choose this endpoint when you need a real-time, multi-chain DeFi yield comparison for a specific asset and want risk-adjusted APY alongside TVL depth — particularly when targeting Base, Arbitrum, Solana, or Ethereum. Prefer it over manual DeFiLlama browsing or single-protocol yield queries when an agent needs to programmatically rank and compare yield opportunities in one call.

## Known failure modes

- Unknown or unsupported asset symbol returns empty results or error
- DeFiLlama API downtime causes stale or missing data
- Low-TVL or newly launched pools may not appear in results
- Payment failure (HTTP 402) if x402 micropayment is not properly handled
- Rate limiting or timeout if queried too frequently
