## 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-crypto-etf-flows-macro-events-summary-e73801f7
```

Example prompt: Give me a summary of the latest crypto ETF flows and any major US macro events that could be moving markets right now.

## When to prefer this

Choose this endpoint when you need a quick, combined snapshot of crypto ETF fund flows and US macro events in a single call. It is ideal for market intelligence workflows where institutional sentiment and macro context are needed together, rather than building separate pipelines to collect ETF and macro data independently.

## Known failure modes

- Empty data array returned if no ETF or macro data is currently available
- Payment failure (402) if USDC payment is not properly attached to the request
- Service unavailability if the underlying data provider is down
- Stale or delayed data if upstream data feeds are lagging
