# LastLook Data — Last 90 Days of FRED Series

> LastLook Data — Last 90 Days of FRED Series is a paid API for AI agents from api.lastlookdata.com, paid per call via x402, $0.1/call, status unknown (last checked 2026-09-13).

Returns the last 90 days of daily observations for a supported FRED economic data series (e.g. Treasury yields, mortgage rates, CPI, SOFR, oil prices).

## Facts

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 api-lastlookdata-com-7cfe8c60
```

Example prompt: Can you pull the last 90 days of the 10-year Treasury yield (DGS10) from LastLook Data so I can see how rates have trended recently?

## When to prefer this

Use this endpoint when you need a 90-day rolling window of FRED economic data — longer than the 30-day endpoint but without the overhead of a full historical pull. Ideal for trend analysis, chart generation, or comparing recent rate movements across the supported series list (Treasury yields, mortgage rates, SOFR, FEDFUNDS, CPI, oil prices, etc.). Choose this over the /current or /date endpoints when time-series context matters.

## Known failure modes

- Missing or invalid 'id' query parameter — returns 400 or error response
- Unsupported series ID not in the allowed enum — rejected by schema validation
- FRED upstream data unavailable or stale — may return partial or empty dataset
- Payment not completed (x402 protocol failure) — 402 response, no data returned
- Network timeout or service unavailability — 5xx response

## How this service works

LastLook Data — last 90 days of any supported FRED series.

## Output

An array of date-value pairs covering the past 90 calendar days for the requested FRED series — e.g. daily DGS10 yield readings, FEDFUNDS rate levels, or CPI index values — returned as a JSON object with observation dates and corresponding numeric values.
