## 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-df6fcb2b
```

Example prompt: Can you scan the top risk-adjusted DeFi yield pools for USDC right now — I want to see the best APYs and TVL depth across Base, Arbitrum, Solana, and Ethereum so I can decide where to deploy my liquidity?

## When to prefer this

Use this endpoint when an agent needs live, cross-chain DeFi yield intelligence for a specific asset — especially when comparing risk-adjusted APYs and TVL depth across Base, Arbitrum, Solana, and Ethereum simultaneously. Prefer this over manual DeFiLlama browsing or single-chain yield tools when the goal is multi-chain yield arbitrage discovery at low cost per call.

## Known failure modes

- Unknown or unsupported asset symbol returns empty results or error
- DeFiLlama data unavailable causes stale or missing pool data
- Very low-TVL assets may return few or no pools
- Rate limiting or payment failure (HTTP 402) if micropayment not completed
- Network timeout if upstream DeFiLlama API is slow
