## 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 agentdiet-dev-defi-stablecoin-liquidity-pool-yield-arbitrage-scanner-5a3f954c -d '<json body>'
```

Example prompt: Scan across Base, Arbitrum, Solana, and Ethereum and find me the best risk-adjusted yield pools for USDC right now — I want to see the top APYs, TVL depth, and any yield spread arbitrage opportunities.

## When to prefer this

Choose this endpoint when you need real-time, cross-chain DeFi yield data aggregated from DeFiLlama for a specific asset, especially when comparing risk-adjusted APYs and TVL depth across Base, Arbitrum, Solana, and Ethereum in a single call. Prefer this over manual DeFiLlama browsing or single-protocol yield checkers when you need a ranked, arbitrage-aware view across multiple chains simultaneously.

## Known failure modes

- Unknown or unsupported asset symbol returns an error or empty results
- DeFiLlama API downtime may result in stale or unavailable data
- Very low-liquidity or newly launched assets may return sparse pool results
- Payment failure via x402 blocks the request before execution
- Malformed asset string (empty or invalid) rejected by schema validation
