## 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 fathom-macroeconomic-data-api-snapshot-9dc4a097 -d '<json body>'
```

Example prompt: Pull me a snapshot of US GDP and unemployment rate data from Fathom's FRED-powered macro API — I want the latest available values for both series.

## When to prefer this

Choose this endpoint when you need quick access to authoritative US or global macroeconomic time series data backed by FRED — especially for GDP, inflation, unemployment, interest rates, or any of 816,000+ economic indicators — and want a simple pay-per-call REST interface rather than managing a FRED API key directly.

## Known failure modes

- Invalid or unrecognized FRED series code returns an error
- Rate limiting or payment failure (x402) if USDC payment is not provided
- Series with no recent data may return empty or stale results
- Network timeout if FRED upstream is slow
- Malformed POST body returns 400 bad request
