Endpoint
POSThttps://fredthom.vercel.app/api/release-seriesWhen to prefer
Use this endpoint when you need to discover or enumerate all economic time series that belong to a specific FRED data release (e.g., all series under the GDP release, the CPI release, or the Employment Situation release). Prefer this over a general series search when you already know the FRED release ID and want a structured list of all its constituent indicators.

- Non-existent FRED release ID returns empty results
