How this service works
Search FRED for economic series by keyword. Returns top matches ranked by popularity with series IDs, titles, and frequency. Useful when you don't know the exact series ID.
Output
An array of matching FRED series objects, each containing a series ID (e.g. UNRATE), full title, units, data frequency (e.g. Monthly, Weekly), and a popularity score — sorted by popularity descending. Typically returns up to 8 results by default or up to 20 if specified.
Example use cases
Find unemployment indicators for research
“I need to analyze labor market trends. Search FRED for unemployment-related economic series and give me the most popular ones so I can pick the right dataset.”
Locate inflation measurement series
“Can you search the Federal Reserve database for inflation and price index data? I want to see what series are available and which ones get updated most frequently.”
Discover recession risk indicators
“Help me find FRED series that track recession signals and economic slowdown indicators. I'm looking for the most widely-used ones that would be relevant to predicting downturns.”

Endpoint
GEThttps://fred-x402.vercel.app/fred/search?utm_source=zero.xyzWhen to prefer
Use this endpoint when you don't know the exact FRED series ID and need to discover it by keyword. It's the right first step before fetching actual data values. Prefer this over guessing series IDs directly, especially for niche or less common indicators.
Side effects
- Empty query string returns error or no results
- Overly broad or misspelled queries may return irrelevant series
- Limit exceeding 20 is silently capped or returns an error
- Network or upstream FRED API unavailability causes 5xx response
- Payment failure (402) if USDC balance is insufficient
