## 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 x402broker-com-defi-stablecoin-liquidity-pool-yield-arbitrage-scanner-3130eaed
```

Example prompt: What are the top risk-adjusted DeFi yield pools for USDC right now across Base, Arbitrum, Solana, and Ethereum — ranked by APY and TVL depth?

## When to prefer this

Choose this endpoint when you need live, cross-chain DeFi yield comparisons for a specific asset symbol and want risk-adjusted metrics (not just raw APY) alongside TVL depth. It is ideal for yield arbitrage scanning across Base, Arbitrum, Solana, and Ethereum simultaneously, especially when Morpho vault data is relevant. Prefer this over generic DeFi dashboards when you need agent-consumable structured output without manual data aggregation.

## Known failure modes

- Missing or empty 'asset' parameter returns a 400 validation error
- Unknown or unsupported asset symbol returns empty results or error
- DeFiLlama data unavailability causes stale or failed response
- Network timeout if upstream DeFiLlama API is slow
- Payment failure via x402 results in 402 response blocking data access
