Endpoint
POSThttps://fredfathom.vercel.app/api/search?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need to discover or search FRED economic time series by keyword before retrieving specific data. It is ideal for agents that need to explore what macroeconomic indicators are available (e.g., GDP variants, CPI measures, regional unemployment) before committing to a specific series ID. Prefer this over direct FRED API access when you want a lightweight, pre-built search layer with micropayment support via x402.
Side effects
- Missing required 'query' field returns validation error
- Empty or overly broad query may return irrelevant or too many series
- Misspelled economic terms may yield zero results
- 'limit' passed as non-string may cause type errors
- Downstream FRED API unavailability causes 503 or empty response
- Query too narrow may return zero matching series
