## 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 polymarket-odds-agentdiet-dev-defi-stablecoin-liquidity-pool-yield-349485b7 -d '<json body>'
```

Example prompt: What are the top risk-adjusted DeFi yield pools for USDC right now across Base, Arbitrum, Solana, and Ethereum — show me APYs, TVL depth, and how the spreads compare?

## When to prefer this

Choose this endpoint when you need a cross-chain, multi-protocol yield comparison for a specific asset in real time, particularly when risk-adjusted APY and TVL depth matter alongside raw yield. It is best suited for DeFi yield optimization workflows, portfolio rebalancing decisions, or arbitrage discovery across Base, Arbitrum, Solana, and Ethereum rather than single-protocol queries or CEX yield products.

## Known failure modes

- Unknown or unsupported asset symbol returns empty results or error
- DeFiLlama API downtime may cause stale or missing APY data
- Very new or low-liquidity assets may return few or no pools
- Network timeout if upstream data providers are slow
- Malformed asset symbol (empty string) rejected by schema validation
