## 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-8294f224 -d '<json body>'
```

Example prompt: Can you scan across Base, Arbitrum, Solana, and Ethereum and find me the best risk-adjusted yield pools for USDC right now, including 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 comparisons rather than raw APY alone. It is ideal for agents helping users optimize capital allocation across Base, Arbitrum, Solana, and Ethereum without manually querying DeFiLlama. Prefer this over generic DeFi dashboards when you need structured, machine-readable yield data with TVL depth signals baked in.

## Known failure modes

- Unknown or unsupported asset symbol returns empty or error response
- DeFiLlama API downtime may cause stale or missing APY data
- Very low-liquidity assets may return no pools or incomplete TVL data
- Rate limiting or payment failure (HTTP 402) if USDC micropayment not processed
- Invalid asset string (empty or malformed) rejected by schema validation
