## 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 shopify-spy-agentdiet-dev-defi-stablecoin-liquidity-pool-yield-820ee733
```

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

## When to prefer this

Choose this endpoint when you need live, cross-chain DeFi yield data for a specific asset and want risk-adjusted comparisons rather than raw APY alone. It is ideal for agents that automate yield allocation decisions, compare stablecoin farming opportunities, or monitor yield spreads across Base, Arbitrum, Solana, and Ethereum in a single call.

## Known failure modes

- Invalid or unrecognized asset symbol returns an error or empty result set
- DeFiLlama API downtime causes stale or missing pool data
- Low-liquidity or niche assets may return very few or no matching pools
- Network timeout if upstream DeFiLlama data is slow to respond
- Payment failure (402) if x402 micropayment is not included or rejected

## How this service works

## Output

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