## 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-calendar-api-d03fe485 -d '<json body>'
```

Example prompt: Show me the next 15 upcoming macroeconomic calendar events — things like Fed meetings, jobs reports, CPI releases — using the Fathom FRED-powered calendar.

## When to prefer this

Use this endpoint when you need a forward-looking schedule of upcoming macroeconomic data releases and events rather than historical time-series values. It is ideal for agents that need to anticipate market-moving events, build economic calendars, or monitor scheduled announcements like FOMC meetings, jobs reports, or inflation data releases.

## Known failure modes

- Invalid limit value (non-numeric string) may return an error or default to 15
- Network timeout if FRED data source is slow to respond
- Empty events array if no upcoming events are scheduled in the near term
- Payment failure (x402) if USDC balance is insufficient
