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.
Example use cases
Track mortgage rate trends for borrowers
“Pull the last 90 days of 30-year mortgage rates so I can show our clients how rates have moved and help them decide on timing for refinancing.”
Monitor Fed policy impact on SOFR
“Get me the last 90 days of SOFR data so I can analyze how recent Fed decisions have influenced short-term lending rates.”
Analyze crude oil price volatility
“Can you grab the last 90 days of crude oil prices so I can brief the team on recent energy market movements and what's driving them?”
Technical details
Endpoint
GEThttps://api.lastlookdata.com/api/series/90When to prefer
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.
Side effects
- 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
