## 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 whale-momentum-agentdiet-dev-defi-stablecoin-liquidity-pool-yield-5692736d
```

Example prompt: Scan all the top DeFi liquidity pools for USDC and show me the best risk-adjusted yields right now — include APY, TVL, and which chains are offering the highest spreads.

## When to prefer this

Choose this endpoint when you need real-time, multi-chain DeFi yield comparison for a specific asset with risk adjustment context. It is especially useful for agents managing treasury yield optimization, yield arbitrage strategies, or DeFi portfolio allocation decisions, as it aggregates DeFiLlama data across the four most active EVM and non-EVM chains in a single call.

## Known failure modes

- Missing or invalid asset symbol returns a validation error
- Unknown asset symbol with no matching pools returns empty results
- DeFiLlama data latency may cause stale APY snapshots
- Rate limiting or payment failure (HTTP 402) if USDC micropayment not processed
- Pools with very low TVL may appear in results but carry higher risk
