## 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-9d1a36ba
```

Example prompt: Scan the top risk-adjusted DeFi yield pools for USDC across Base, Arbitrum, Solana, and Ethereum right now — I want to see which pools have the best APYs and TVL depth so I can decide where to deploy capital.

## When to prefer this

Choose this endpoint when you need a cross-chain, risk-adjusted view of DeFi yield opportunities for a specific asset — especially if you want DeFiLlama-sourced APYs and TVL depth in a single call rather than manually querying multiple protocol APIs. Prefer this over single-protocol or single-chain yield APIs when the goal is yield arbitrage or capital allocation across ecosystems.

## Known failure modes

- Unknown or unsupported asset symbol returns empty or error response
- DeFiLlama API downtime may cause stale or missing data
- Very low-liquidity assets may return few or no pools
- Payment failure (HTTP 402) if x402 USDC micropayment is not properly handled

## How this service works
