## 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-64a89520
```

Example prompt: Scan live DeFi pools for USDC and show me the top risk-adjusted yield opportunities across Base, Arbitrum, Ethereum, and Solana — I want to see APYs, TVL, and yield spreads so I can decide where to deploy.

## When to prefer this

Choose this endpoint when you need live, multi-chain DeFi yield data for a specific asset and want risk-adjusted comparisons across major chains (Base, Arbitrum, Solana, Ethereum) in a single call. Prefer this over manual DeFiLlama browsing or chain-specific tools when you need cross-chain yield arbitrage signals or TVL-weighted APY rankings for agent-driven capital allocation decisions.

## Known failure modes

- Unknown or unsupported asset symbol returns empty results or error
- DeFiLlama data temporarily unavailable causing stale or missing APY data
- Network timeout if upstream data source is slow
- Invalid asset parameter (empty string) returns 400 validation error
- Payment failure (HTTP 402) if x402 micropayment not completed

## How this service works
