Technical details
Endpoint
POSThttps://fredthom.vercel.app/api/sourcesWhen to prefer
Use this endpoint when you need to discover what macroeconomic data sources are available before querying specific time series. Ideal as a first step in a workflow where you need to identify the right source for GDP, CPI, unemployment, interest rate, or other macro data. Prefer over direct FRED API when you want a managed, pay-per-call interface without managing your own FRED API key.
Side effects
- 402 Payment Required if USDC payment of $0.35 not provided via x402 protocol
- 500 server error if the underlying FRED connection is unavailable
- Empty or partial source list if upstream FRED API is rate-limited
- Timeout if the Vercel serverless function exceeds execution limits
