## 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 alpha-stream-agentdiet-dev-defi-stablecoin-liquidity-pool-yield-67cbb624
```

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

## When to prefer this

Choose this endpoint when you need live, cross-chain DeFi yield comparison for a specific asset and care about risk-adjusted APY and TVL depth — not just raw APY. It is best suited for agents making capital allocation decisions across Base, Arbitrum, Solana, and Ethereum stablecoin or token pools. Prefer this over generic DeFi dashboards when you need structured, agent-consumable yield data via a pay-per-call API.

## Known failure modes

- Missing or empty 'asset' parameter returns a validation error
- Unknown or unsupported asset symbol may return empty results or an error
- DeFiLlama data unavailability or API downtime may cause stale or failed responses
- Rate limiting or payment failure (HTTP 402) if the per-call fee is not settled
