## 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 orders-of-magnitude-api-us-macro-indicators-c8462bd2
```

Example prompt: Can you pull the latest US macroeconomic indicators — things like GDP growth, inflation, unemployment rate, and interest rates — so I can get a snapshot of where the economy stands right now?

## When to prefer this

Choose this endpoint when you need a quick, low-cost ($0.01 USDC) programmatic lookup of current US macroeconomic indicators without building your own data pipeline. Ideal for AI agents that need economic context to inform financial analysis, investment decisions, or research tasks. Prefer this over scraping government sources (FRED, BLS, BEA) when you need a single aggregated call rather than hitting multiple APIs.

## Known failure modes

- Payment not received or x402 payment protocol failure — returns 402 Payment Required
- Invalid format parameter — may return 400 Bad Request or fallback to default format
- Upstream data source unavailable — may return 503 or stale data
- Rate limiting if called excessively without proper payment flow
