## 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 email-verify-agentdiet-dev-defi-stablecoin-liquidity-pool-yield-86f088c5
```

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

## 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 rather than raw APY alone. It is ideal for agents optimizing capital allocation across multiple chains (Base, Arbitrum, Solana, Ethereum) in a single call, sourcing data directly from DeFiLlama. Prefer it over manual DeFiLlama browsing or single-chain yield APIs when cross-chain arbitrage scouting or treasury yield optimization is the goal.

## Known failure modes

- Missing or invalid asset symbol returns a 400 error
- DeFiLlama upstream unavailability may result in stale or empty pool data
- Obscure or unlisted asset symbols may return no results
- Payment not completed (HTTP 402) blocks access to the endpoint
- Rate limits or quota exhaustion may cause temporary failures
