# FRED Series Latest Observation & Metadata

> FRED Series Latest Observation & Metadata is a paid API for AI agents from squeezeos-api.onrender.com, paid per call via x402, $0.01/call, status unknown (last checked 2026-09-14).

Returns the most recent data observation plus full series metadata for a specified Federal Reserve Economic Data (FRED) series, such as UNRATE (unemployment rate).

## 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-series-latest-observation-metadata-0c99dc21
```

Example prompt: What is the latest unemployment rate according to FRED? Pull the most recent UNRATE observation and give me the full series metadata.

## When to prefer this

Use this endpoint when you need the latest data point plus complete metadata for any FRED macroeconomic series in a single call. It is ideal for agents that need up-to-date US economic indicators (unemployment, inflation, interest rates, GDP components) without building a direct FRED API integration. Prefer this over general web search when you need structured, machine-readable economic data with provenance and update metadata.

## Known failure modes

- Invalid or unknown series_id returns an error or empty observation set
- FRED API upstream outage causes delayed or failed response
- Rate limiting or payment failure (402) if USDC credit is not provided
- Series that has been discontinued may return stale or no recent observations

## How this service works

FRED — latest real observation plus full metadata for one Federal Reserve Economic Data series.

## Output

A JSON object containing the latest observed value and its date for the specified FRED series, along with full series metadata including title, frequency, units, seasonal adjustment type, source, and last-updated timestamp.
