## 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-x402-vercel-app-cd4131c6
```

Example prompt: What's the latest unemployment rate from FRED? Use series ID UNRATE and tell me the value, date, and units.

## When to prefer this

Use this endpoint when you need the single most recent data point for a specific FRED economic series and do not need historical data. Ideal for real-time dashboards, quick macro checks, or answering point-in-time economic questions. Prefer this over the historical endpoint when only the current value matters, and over the search endpoint when you already know the series ID or a common name like 'inflation' or 'unemployment'.

## Known failure modes

- Unknown or misspelled series ID returns an error or empty result
- Plain-English name resolution may not map correctly to obscure series
- FRED API rate limits or outages cause upstream failures
- Series with no recent data returns stale or missing latest_value
- Payment not processed results in 402 response before data is returned

## How this service works

Latest value for any FRED economic series. Accepts series ID (e.g. CPIAUCSL) or plain-English name (e.g. 'inflation', 'unemployment', 'fed rate'). Returns value, units, date, frequency.

## Output

Returns a JSON object with the series ID, full title, latest numeric value, the date of that observation, units (e.g. '%', 'Billions of Dollars'), reporting frequency (e.g. 'M' for monthly), seasonal adjustment status, last updated timestamp, and descriptive notes about the series.
