## 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-40af3e9e
```

Example prompt: Can you scan all the top DeFi liquidity pools for USDC and show me which ones have the best risk-adjusted APY right now across Base, Arbitrum, Solana, and Ethereum?

## When to prefer this

Use this endpoint when you need real-time, cross-chain DeFi yield data for a specific asset and want risk-adjusted comparisons rather than raw APY alone. It is ideal for yield optimization workflows, DeFi portfolio rebalancing decisions, and stablecoin arbitrage scanning. Prefer this over manual DeFiLlama browsing when you need structured, agent-consumable output with TVL depth context across Base, Arbitrum, Solana, and Ethereum simultaneously.

## Known failure modes

- Unrecognized or misspelled asset symbol returns empty or error response
- DeFiLlama data unavailable or rate-limited causing stale or missing APY data
- Asset has no major pools on the supported chains resulting in empty results
- Network errors to upstream DeFiLlama API causing timeout or partial data
- Payment failure via x402 protocol blocking the request
