## 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-b4cdc5c8 -d '<json body>'
```

Example prompt: Scan live DeFi pools for USDC and show me the best risk-adjusted APYs and TVL depth across Base, Arbitrum, Solana, and Ethereum right now.

## When to prefer this

Choose this endpoint when you need real-time, cross-chain DeFi yield intelligence grounded in DeFiLlama data — specifically for comparing APYs, TVL depth, and risk-adjusted spreads for a specific asset across Base, Arbitrum, Solana, and Ethereum. Prefer it over generic DeFi dashboards when you need programmatic, agent-callable yield data without manual UI interaction.

## Known failure modes

- Unknown or unsupported asset symbol returns empty or error response
- DeFiLlama data unavailability causes stale or missing pool entries
- Very low-liquidity assets may return few or no pools
- Network timeouts if DeFiLlama upstream is slow
- Invalid input (empty asset field) triggers schema validation error
