## 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-fred-releases-2997be0f -d '<json body>'
```

Example prompt: Pull up the list of available FRED macroeconomic data releases — give me the first 50 entries with just the dates included.

## When to prefer this

Use this endpoint when you need to discover or catalog the available macroeconomic data releases published by FRED — for example, to enumerate dataset names before querying specific series, to build a release calendar, or to identify which economic indicators are available. Prefer this over a general web search when you need structured, machine-readable release metadata directly from the FRED catalog.

## Known failure modes

- Invalid limit value (non-numeric string) may return an error or default to 20
- Empty releases array if FRED upstream is unavailable
- Source field present but releases array missing if upstream data is incomplete
- Network timeout if the FRED data proxy is slow to respond

## How this service works

Free macroeconomic data API powered by FRED. 816,000+ economic time series. GDP, inflation, unemployment, interest rates, and more.

## Output

Returns a JSON object with a source field (identifying FRED as the data provider) and a releases array containing release objects — each representing a named FRED data release schedule. When dates-only mode is enabled, only release date information is returned rather than full release metadata.
