## 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-9168cbda
```

Example prompt: What are the best risk-adjusted DeFi yield pools for USDC right now — scan across Base, Arbitrum, Solana, and Ethereum and show me the top APYs with TVL depth?

## When to prefer this

Choose this endpoint when you need real-time, cross-chain DeFi yield comparison for a specific asset — especially when you need risk-adjusted APY data with TVL depth from DeFiLlama across Base, Arbitrum, Solana, and Ethereum simultaneously. Prefer this over manual protocol-by-protocol lookups or CEX rate comparisons when the goal is DeFi liquidity pool yield arbitrage or capital allocation optimization.

## Known failure modes

- Missing or invalid asset symbol returns a validation error
- Unknown or unsupported asset symbol returns empty or null pool results
- DeFiLlama data unavailability may cause stale or incomplete yield data
- Network timeout if upstream DeFiLlama API is slow
- Payment failure via x402 returns HTTP 402 before any data is served
