## 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 json-repair-agentdiet-dev-defi-stablecoin-liquidity-pool-yield-84be6767
```

Example prompt: What are the top risk-adjusted DeFi yield pools for USDC right now across Base, Arbitrum, Solana, and Ethereum — rank them by APY and TVL depth so I can see the best opportunities?

## 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 context rather than just raw rates. It is especially useful for agents performing yield optimization, treasury management, or arbitrage scouting across Base, Arbitrum, Solana, and Ethereum simultaneously using DeFiLlama as the underlying data source.

## Known failure modes

- Unknown or unsupported asset symbol returns empty results or error
- DeFiLlama data unavailability causes stale or missing APY data
- Rate limiting or payment failure (HTTP 402) if USDC micropayment not processed
- Malformed asset parameter (empty string) triggers validation error
- Network timeouts if upstream DeFiLlama API is slow or down

## How this service works

## Output

Returns a ranked list of DeFi liquidity pools for the specified asset, including live APY rates sourced from DeFiLlama, TVL depth, risk-adjusted yield spreads, and pool metadata across Base, Arbitrum, Solana, and Ethereum networks.
