## 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 x402-audit-agentdiet-dev-defi-stablecoin-liquidity-pool-yield-e25b3136
```

Example prompt: Scan all major DeFi pools for USDC and show me the top risk-adjusted yields with TVL depth across Base, Arbitrum, Solana, and Ethereum.

## When to prefer this

Choose this endpoint when you need live, multi-chain DeFi yield data for a specific asset and want risk-adjusted APY comparisons with TVL depth rather than just raw rates. Prefer this over generic crypto price APIs when the goal is yield optimization or liquidity pool selection across Base, Arbitrum, Solana, and Ethereum.

## Known failure modes

- Unknown or unsupported asset symbol returns empty results or error
- DeFiLlama data temporarily unavailable causes stale or missing APY data
- Network timeout for live data fetch returns error
- Payment not processed (HTTP 402) if x402 payment header is missing or invalid

## How this service works

## Output

Returns a ranked list of DeFi liquidity pools for the requested asset, including live APY rates sourced from DeFiLlama, TVL depth figures, risk-adjusted yield spreads, and chain attribution (Base, Arbitrum, Solana, Ethereum) to help identify optimal yield opportunities.
