## 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-61769e9e
```

Example prompt: Scan all major DeFi pools across Base, Arbitrum, Solana, and Ethereum and show me the top risk-adjusted yield opportunities for USDC right now, including APYs and TVL depth.

## When to prefer this

Choose this endpoint when you need a real-time, multi-chain comparison of DeFi yield opportunities for a specific asset, particularly when risk-adjusted spreads and TVL depth matter for decision-making. It is best suited for agents performing yield optimization, portfolio rebalancing research, or DeFi arbitrage scanning across Base, Arbitrum, Solana, and Ethereum simultaneously.

## Known failure modes

- Missing or empty 'asset' parameter returns a validation error
- Unknown or unsupported asset symbol may return empty results or an error
- DeFiLlama data unavailability may cause stale or missing yield data
- Payment failure (HTTP 402) if x402 micropayment is not correctly handled
- Rate limiting or timeout if upstream DeFiLlama APIs are slow
