How this service works
Free macroeconomic data API powered by FRED. 816,000+ economic time series. GDP, inflation, unemployment, interest rates, and more.
Output
A JSON object containing the original query string, total count of matching series, the source identifier ('FRED'), and an array of economic time series objects matching the search keywords — each series likely includes metadata such as series ID, title, frequency, units, and observation dates.
Example use cases
Example prompt
“Search the Fathom FRED macroeconomic database for time series related to 'inflation rate' and return the top 5 results so I can see what economic indicators are available.”
Technical details
Endpoint
POSThttps://fredthom.vercel.app/api/searchWhen to prefer
Use this endpoint when you need to discover and identify specific economic time series from the FRED database by keyword before fetching their actual data. Ideal for agents that need to map a natural-language economic concept (e.g. 'core PCE inflation') to a specific FRED series ID. Prefer this over direct FRED API access when using x402 micropayment-enabled infrastructure or when you want a simplified search interface over the full 816,000+ series catalog.
Side effects
- Missing required 'query' field returns a validation error
- Empty or overly generic query may return irrelevant or no series
- Network timeout if FRED upstream is slow or unavailable
- Invalid limit value (non-numeric string) may cause unexpected behavior
- Payment failure (402) if USDC payment is not properly attached
