## 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-6e98bb55
```

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

## When to prefer this

Use this endpoint when you need live, multi-chain DeFi yield data for a specific asset and want risk-adjusted comparisons rather than raw APY alone. Prefer this over general DeFi dashboards when an agent needs structured, queryable yield data programmatically, especially for USDC, ETH, SOL, or WBTC across Base, Arbitrum, Solana, and Ethereum.

## Known failure modes

- Invalid or unsupported asset symbol returns an error or empty result
- DeFiLlama data unavailable due to upstream outage may return stale or missing data
- Very new or low-liquidity assets may have no matching pools
- Missing required 'asset' parameter returns a validation error
