## 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-95442240
```

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

## When to prefer this

Choose this endpoint when you need live, cross-chain DeFi yield comparisons for a specific asset and want risk-adjusted rankings rather than raw APY listings. It is ideal for agents making yield optimization decisions, treasury management bots, or DeFi arbitrage workflows that need TVL-depth-aware pool selection across Base, Arbitrum, Solana, and Ethereum simultaneously. Prefer this over generic DeFi aggregators when you need a single API call that already applies risk-adjustment scoring.

## Known failure modes

- Missing or invalid asset symbol returns a validation error
- Unsupported or unknown asset symbols may return empty results or no matching pools
- DeFiLlama data unavailability or upstream API outage may cause stale or missing yield data
- Pools with extremely low TVL may be filtered out or flagged as high-risk
- Network-specific outages (e.g. Solana RPC issues) may result in incomplete cross-chain data
