## 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 json-repair-agentdiet-dev-defi-stablecoin-liquidity-pool-yield-0437c713 -d '<json body>'
```

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

## When to prefer this

Choose this endpoint when you need a real-time, multi-chain DeFi yield comparison for a specific asset with risk-adjusted scoring and TVL context. It is ideal for yield optimization agents, DeFi arbitrage bots, or portfolio rebalancing workflows that need to compare APYs and liquidity depth across Base, Arbitrum, Solana, and Ethereum simultaneously, sourced from DeFiLlama.

## Known failure modes

- Invalid or unsupported asset symbol returns an error or empty results
- DeFiLlama data temporarily unavailable causes stale or missing APY data
- Network timeout if upstream data aggregation takes too long
- Payment required (HTTP 402) if x402 micropayment header is missing or insufficient
- Very low TVL pools may be returned but flagged as high-risk
