Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## 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-72804e00
```

Example prompt: Scan live DeFi pools for USDC and show me the top risk-adjusted yields across Base, Arbitrum, Solana, and Ethereum — I want to see APY, TVL depth, and how the spreads compare.

## When to prefer this

Choose this endpoint when you need real-time, cross-chain DeFi yield comparisons for a specific asset, particularly when risk-adjusted returns and TVL depth matter — not just raw APY. It is ideal for yield arbitrage scanning across Base, Arbitrum, Solana, and Ethereum simultaneously, pulling live DeFiLlama data in one call rather than querying each protocol individually.

## Known failure modes

- Missing or invalid asset symbol returns a validation error
- Unknown or unsupported asset symbol may return empty pool results
- DeFiLlama data unavailability may cause stale or missing APY data
- Network timeouts if upstream DeFiLlama API is slow
- Payment failure (HTTP 402) if USDC micropayment is not provided

## How this service works

Scans live DeFiLlama APYs, TVL depth, and risk-adjusted yield spreads across Base, Arbitrum, Solana, and Ethereum pools. (Live x402 v2, IETF MPP & MCP endpoint at https://whale-momentum.agentdiet.dev/v1/lending-rates)

## Output

Returns a structured object containing ranked DeFi pool data for the requested asset, including live APY rates sourced from DeFiLlama, TVL depth per pool, risk-adjusted yield spreads, and cross-chain comparisons across Base, Arbitrum, Solana, and Ethereum.
