## 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 defi-yield-agentdiet-dev-defi-stablecoin-liquidity-pool-yield-01dec7a5
```

Example prompt: Scan DeFiLlama for the best risk-adjusted USDC yield pools across Base, Arbitrum, Solana, and Ethereum right now and show me the top opportunities by APY 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 APY comparisons across multiple chains (Base, Arbitrum, Solana, Ethereum) in a single call. Prefer it over manual DeFiLlama browsing or on-chain queries when you need aggregated, ranked yield opportunities with TVL context for yield optimization or arbitrage discovery.

## 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 API downtime or rate limiting may cause stale or failed responses
- Payment failure (HTTP 402) if the $0.01 per-call fee is not fulfilled via x402
- Network timeout if the live data scan takes too long
