## 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 serp-extract-agentdiet-dev-defi-stablecoin-liquidity-pool-yield-b98fd8c1 -d '<json body>'
```

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

## 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 across multiple ecosystems (Base, Arbitrum, Solana, Ethereum) in a single call. Prefer this over manually querying individual protocol dashboards or single-chain yield APIs when the goal is yield arbitrage discovery or portfolio reallocation decisions.

## Known failure modes

- Missing or empty 'asset' field 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
- Rate limiting or payment failure (HTTP 402) if x402 payment is not processed
- Network timeouts if upstream DeFiLlama API is slow
