## 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 domain-osint-agentdiet-dev-defi-stablecoin-liquidity-pool-yield-a6a7854e
```

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

## When to prefer this

Use this endpoint when you need live, cross-chain DeFi yield comparisons for a specific asset and want risk-adjusted APY and TVL data sourced from DeFiLlama. It is especially useful for automated treasury allocation, yield arbitrage research, or portfolio optimization agents that need to compare pools across Base, Arbitrum, Solana, and Ethereum in a single call.

## Known failure modes

- Missing or invalid asset symbol returns a validation error
- Unknown or unsupported asset symbol may return empty results
- DeFiLlama API downtime could result in stale or unavailable data
- Rate limiting or payment failure (HTTP 402) if x402 payment is not completed
- Response schema is generic object — structured field presence may vary
