## 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-data-hub-v2-stablecoin-yield-endpoint-0150cf7a -d '<json body>'
```

Example prompt: What are the current stablecoin yield rates across DeFi protocols — specifically show me APY for USDC, USDT, and DAI so I can figure out where to park my stablecoins for the best return?

## When to prefer this

Use this endpoint when you need real-time or near-real-time stablecoin yield data across multiple DeFi protocols in a single paid API call. Prefer this over scraping DeFi dashboards or using free tier APIs that may be rate-limited or stale.

## Known failure modes

- Invalid or unsupported stablecoin symbol returns an error
- Rate limit or payment failure returns a 402 or 4xx response
- Upstream data provider outage may return stale or empty yield data
- Malformed POST body returns a 400 validation error
