## 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 etf-macro-intelligence-weekly-data-be732bca
```

Example prompt: Pull this week's crypto ETF fund flows and institutional data — I want to see which Bitcoin and Ethereum ETFs had the biggest inflows or outflows and any major US macro events that could be moving the market.

## When to prefer this

Choose this endpoint when you need a combined weekly view of crypto ETF institutional flows and US macro events in a single call, priced at $0.02 USDC per request. Prefer this over general financial data APIs when the use case is specifically crypto ETF fund-flow intelligence paired with macro context, and when payment is made via the x402 protocol.

## Known failure modes

- Empty data array returned if no weekly data is yet available for the current period
- Payment failure (402) if USDC payment is not included or is insufficient
- Rate limiting or server errors (5xx) from the Vercel deployment
- Stale or delayed data if the upstream data source hasn't refreshed for the current week
