## 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-50133af8 -d '<json body>'
```

Example prompt: Pull me a snapshot of US GDP and unemployment rate data from FRED — I need the most recent observations for both series to put together an economic overview.

## When to prefer this

Choose this endpoint when you need reliable, authoritative macroeconomic data drawn from the FRED database (816,000+ series) and want a simple pay-per-call model without managing API keys or FRED authentication. Ideal for agents that need GDP, inflation, unemployment, interest rates, or other US and global economic time series on demand. Prefer this over direct FRED API calls when you want a unified x402-compatible micropayment interface for economic data retrieval.

## Known failure modes

- Invalid or unrecognized FRED series ID returns an error
- Requested date range outside available data history returns empty or partial results
- Payment of 0.2 USDC not completed causes 402 Payment Required response
- FRED API upstream outage causes service unavailability
- Malformed POST body causes 400 Bad Request
