## 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-macro-indicators-cac59d38
```

Example prompt: Pull the latest macro indicators for DFF, DGS10, CPIAUCSL, and UNRATE — I want to see the federal funds rate, 10-year Treasury yield, CPI, and unemployment rate to understand the current macro environment.

## When to prefer this

Choose this endpoint when you need structured US macroeconomic time-series data — particularly Fed policy rates, Treasury yields, CPI, or unemployment — especially in the context of crypto ETF analysis or institutional market intelligence. It is well-suited for agents that need to correlate macro conditions with digital asset market behavior.

## Known failure modes

- Missing or invalid 'series' query parameter returns an error or empty data array
- Unrecognized series codes produce empty results with no data points
- Network or upstream data provider outage results in failed fetch
- Rate limiting or payment failure (x402) blocks the request

## How this service works

Crypto ETF flows, institutional fund data, and US macroeconomic events.

## Output
