Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## 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 saylor-innovations-data-desk-fred-economic-series-lookup-e2d0f6ec
```

Example prompt: What's the current US unemployment rate — give me the latest UNRATE value, how it's changed versus last period and year-over-year, plus the last 12 monthly readings?

## When to prefer this

Choose this endpoint when you need a ready-to-use economic data summary for any FRED series — particularly when you want not just the raw latest value but also change metrics, year-over-year context, and recent historical observations in a single call. It is ideal for agents building economic dashboards, briefings, or monitoring workflows without needing to query and process raw FRED data directly. Prefer it over direct FRED API access when you need pre-computed change and YoY statistics without additional calculation steps.

## Known failure modes

- Invalid or unknown FRED series ID returns an error or empty result
- FRED API upstream outage may delay or block data retrieval
- Limit parameter outside 1–200 range may be rejected or clamped
- Very new or recently discontinued series may have sparse or missing observations
- Payment failure (x402) prevents endpoint access

## How this service works

Economic data series - latest value, change, year-over-year, window high and low and recent history for any FRED series such as unemployment, CPI, fed funds or GDP

## Output

A JSON object containing: the FRED series ID and title, units of measure, data frequency, latest observation (date + value), previous observation, year-ago value, absolute change and percent change vs previous period, year-over-year change and percent, window high and low within the recent observation window, an array of recent observations (up to 200, default 24), the data source attribution, and a timestamp of when the data was checked (UTC).
