Technical details
Endpoint
GEThttps://agent402.tools/api/fred-searchWhen to prefer
Use this endpoint when you need to discover FRED economic time series by keyword before fetching actual data. Ideal as the first step in a two-call workflow: search here to get a series ID, then call /api/fred-series to retrieve the actual data values. Prefer this over manually guessing FRED series IDs, which are non-obvious alphanumeric codes.

- Limit outside 1-100 range may return an error or be clamped
- Obscure or misspelled search terms may return zero results
- Payment of 0.005 USDC required; unpaid requests return 402 Payment Required
