Endpoint
POSThttps://fredfathom.vercel.app/api/popularWhen to prefer
Use this endpoint when you need to discover which macroeconomic time series are most popular or relevant before fetching specific data, or when you want a curated starting set of economic indicators (GDP, inflation, unemployment, interest rates) without knowing exact FRED series IDs. Prefer this for economic research bootstrapping, dashboard population, or macroeconomic monitoring setup.

- Rate limiting or server unavailability on the Vercel deployment
- Empty or malformed response if FRED upstream is unavailable
