## 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-1ac96996 -d '<json body>'
```

Example prompt: What are the current APY rates for USDC and USDT across major DeFi yield protocols like Aave and Compound — show me the top options sorted by yield?

## When to prefer this

Use this endpoint when you need live, aggregated stablecoin yield data across multiple DeFi protocols in a single call, especially when building yield comparison tools, treasury management workflows, or DeFi dashboards. It is part of a broader x402 paid data hub, so it is preferable when you need crypto-native data with micropayment access rather than scraping individual protocol UIs.

## Known failure modes

- Payment not provided or rejected — x402 payment required before data is returned
- Invalid or unsupported stablecoin symbol in request body
- Rate limit exceeded for the paid endpoint
- Upstream data source unavailable causing stale or missing yield data
- Malformed POST body resulting in 400 error
