## 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 fred-economic-data-release-calendar-5b9dd682 -d '<json body>'
```

Example prompt: What economic data releases does FRED have scheduled over the next 60 days? I'm especially interested in anything related to inflation — search by release name for 'CPI'.

## When to prefer this

Use this endpoint when you need a forward-looking or near-term schedule of specific FRED economic data releases, especially when filtering by release name or ID. Prefer this over bulk FRED API access when you only need the calendar/scheduling metadata (dates, press-release flags, publisher links) rather than the actual data observations. Ideal for agents that need to trigger downstream actions around known publication dates.

## Known failure modes

- Window exceeds 366 days — request rejected with validation error
- Invalid release ID — returns empty results or not-found error
- Release name search with no matches — returns empty list
- Date window in the past with no historical releases — returns empty list
- FRED upstream unavailable — service may return a gateway or timeout error

## How this service works

Returns scheduled economic-data release dates from the Federal Reserve Bank of St. Louis for a caller-selected window of at most 366 days. Results can be restricted by release id or searched by release name and include the publisher link and press-release flag from the FRED release directory. This is an on-demand calendar lookup, not a mirror or bulk export. Dates are source publication dates and do not guarantee that observations are already available in FRED.

## Output

A list of scheduled economic-data release dates within the requested window, each entry including the release name, scheduled publication date, publisher link, press-release flag, and release ID. Dates reflect FRED's planned source publication schedule and do not confirm that observations are already available.
