## 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-4f8c5e40 -d '<json body>'
```

Example prompt: What are the top risk-adjusted DeFi yield pools for USDC right now across Base, Arbitrum, Solana, and Ethereum — show me APY, TVL depth, and spread comparisons?

## When to prefer this

Choose this endpoint when you need live, multi-chain DeFi yield data for a specific asset and want risk-adjusted comparisons rather than raw APY alone. It is particularly useful for yield optimization agents, treasury management bots, or DeFi arbitrage scanners that need TVL-weighted pool rankings across Base, Arbitrum, Solana, and Ethereum simultaneously. Prefer this over manual DeFiLlama queries when you need structured, agent-consumable output with spread analysis built in.

## Known failure modes

- Unsupported or misspelled asset symbol returns an error or empty results
- DeFiLlama data temporarily unavailable causes stale or missing yield data
- Very low-liquidity assets may return few or no pools
- Network-specific outages may cause incomplete cross-chain coverage
- Rate limiting or payment failure (402) blocks the request

## How this service works
