## 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 alpha-stream-agentdiet-dev-defi-stablecoin-liquidity-pool-yield-9146d576
```

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

## When to prefer this

Choose this endpoint when you need live, multi-chain DeFi yield comparisons for a specific asset with risk-adjusted scoring and TVL depth signals. It is preferable over manual DeFiLlama browsing or single-chain yield aggregators when the user needs a cross-chain arbitrage view in a single call.

## Known failure modes

- Missing required '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 APY data
- Network timeout if upstream DeFiLlama API is slow
- Payment failure via x402 blocks access to results

## How this service works

## Output

Returns a ranked list of DeFi liquidity pools for the queried asset, including live APY rates sourced from DeFiLlama, TVL depth figures, risk-adjusted yield spreads, and chain-specific breakdowns across Base, Arbitrum, Solana, and Ethereum.
