## 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 hn-pulse-agentdiet-dev-defi-stablecoin-liquidity-pool-yield-arbitrage-1b434122
```

Example prompt: Scan the top risk-adjusted DeFi yield pools for USDC right now — I want to see the best APYs and TVL depth across Base, Arbitrum, Solana, and Ethereum so I can figure out where to deploy capital.

## When to prefer this

Choose this endpoint when you need live, cross-chain DeFi yield data for a specific asset and want risk-adjusted comparisons rather than raw APY numbers. It is especially useful for yield arbitrage scanning across Base, Arbitrum, Solana, and Ethereum simultaneously. Prefer it over manually querying DeFiLlama when you need aggregated, ranked pool data in a single API call.

## Known failure modes

- Unknown or unsupported asset symbol returns empty results or an error
- DeFiLlama data unavailability causes stale or missing APY data
- Network-specific pools unavailable if a chain is temporarily unresponsive
- Payment failure (HTTP 402) if x402 microtransaction is not completed
- Malformed asset symbol (e.g. empty string) returns a 400 validation error
