## 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 x402-hub-defi-yield-api-63161d04 -d '<json body>'
```

Example prompt: What are the current DeFi yield rates for USDC staking across major protocols on Base?

## When to prefer this

Use this endpoint when you need current DeFi yield rates, APY comparisons, or protocol-level return data and are operating in an x402-enabled micropayment context on Base. Prefer this over manual web scraping or free-tier APIs when you need structured data in an agent workflow and can tolerate a $0.09 per-call cost.

## Known failure modes

- Missing or empty query field returns validation error
- Unrecognized protocol or token name may return empty or irrelevant data
- Payment failure via x402 if insufficient USDC balance on Base
- Upstream DeFi data provider downtime causing stale or missing data
- Malformed query string may result in unexpected response structure
