## 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 defi-yield-agentdiet-dev-defi-stablecoin-liquidity-pool-yield-11836479
```

Example prompt: Scan live DeFi pools for USDC and show me the top risk-adjusted yield opportunities across Base, Arbitrum, Solana, and Ethereum — ranked by APY and TVL depth.

## When to prefer this

Choose this endpoint when you need live, multi-chain DeFi yield data for a specific asset, especially when comparing risk-adjusted returns and TVL depth across Base, Arbitrum, Solana, and Ethereum simultaneously. It is ideal for yield arbitrage discovery, DeFi portfolio allocation decisions, and stablecoin treasury optimization. Prefer it over generic DeFiLlama queries when you need the data already filtered, ranked, and risk-adjusted for a single asset symbol.

## Known failure modes

- Missing or invalid asset symbol returns a validation error
- Unknown asset symbol with no matching pools returns empty results
- DeFiLlama data unavailability may result in stale or partial pool data
- Rate limiting or payment failure (402) if micropayment not fulfilled
- Highly illiquid or obscure assets may return few or no pool matches

## 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://defi-yield.agentdiet.dev/api)

## Output

Returns a structured breakdown of top DeFi pools for the queried asset, including APY rates, TVL depth, risk-adjusted yield spreads, pool names, and chain-level comparisons across Base, Arbitrum, Solana, and Ethereum.
