## 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-e3425062
```

Example prompt: Scan the top risk-adjusted DeFi yield pools for USDC across Base, Arbitrum, Solana, and Ethereum right now — show me the best APYs and TVL depth so I can find the best place to park my stablecoins.

## When to prefer this

Choose this endpoint when you need real-time, cross-chain DeFi yield intelligence for a specific asset — particularly when comparing risk-adjusted APYs and TVL depth across Base, Arbitrum, Solana, and Ethereum simultaneously. It is the right choice over manual DeFiLlama browsing or single-chain yield tools when an agent needs structured, actionable yield arbitrage data in one call.

## Known failure modes

- Unknown or unsupported asset symbol returns empty results or an error
- DeFiLlama API downtime causes stale or unavailable yield data
- Very low TVL assets may return few or no ranked pools
- Rate limiting or payment failure results in HTTP 402 or 429 response
