## 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-releases-endpoint-b6126318 -d '<json body>'
```

Example prompt: Can you fetch me the list of macroeconomic data releases available through FRED — just pull the first 10 and include the dates?

## When to prefer this

Use this endpoint when you need to enumerate or browse the top-level catalog of economic data releases from FRED — especially when you want to discover what macro data series are available before querying specific series. Prefer this over searching individual series endpoints when you need a structural overview of release groups (e.g. which release contains CPI, which contains unemployment data).

## Known failure modes

- Invalid 'limit' value (non-numeric string) may cause unexpected truncation or error
- Network timeout if FRED upstream is slow
- Empty releases array if FRED returns no results for the requested configuration
- Missing 'releases' key if source system is unavailable

## 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' string identifying the data provider and a 'releases' array of release objects, each describing a named group of economic time series (e.g. GDP, CPI, unemployment). When 'dates' is true, only date information is returned per release.
