## 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 citiview-fred-economic-series-search-06d90a35
```

Example prompt: Search FRED for economic series related to 'unemployment rate' and show me the top 10 results including their frequency, units, and whether the data can be served.

## When to prefer this

Use this endpoint when you need to discover and identify specific FRED economic time series by topic or keyword before fetching the actual data. It is the right choice when you don't know the exact FRED series ID and need to browse or filter by frequency, units, or seasonal adjustment. Prefer this over general web search when you need structured FRED metadata with serveability flags.

## Known failure modes

- Missing required 'q' keyword parameter returns a 400 validation error
- No matching series found returns an empty result list
- Very broad keywords may return irrelevant or low-quality series
- Copyrighted series are returned in results but flagged as not serveable
- Rate limiting or payment failure may block access at $0.002 per call

## How this service works

Search 800,000+ FRED economic series by keywords, most popular first: id, title, frequency, units, seasonal adjustment, date range and whether the series can be served (copyrighted series are flagged).

## Output

Returns a list of FRED economic series matching the keywords, each with: series ID, title, frequency (e.g. monthly, quarterly), units, seasonal adjustment type, observation date range (start and end), and a flag indicating whether the series can be served (copyrighted series are flagged as unavailable). Results are ordered by popularity.
