Technical details
Endpoint
POSThttps://fredthom.vercel.app/api/bulkWhen to prefer
Use this endpoint when you need to fetch multiple FRED economic time series in a single call rather than making individual requests per series. Ideal for macroeconomic dashboards, economic research, financial analysis workflows, or any agent task requiring simultaneous access to indicators like GDP, CPI, unemployment rate, or interest rates. Prefer over direct FRED API when you want a simplified x402-payable interface without managing FRED API keys.
Side effects
- Invalid or unrecognized FRED series ID returns error or empty result for that series
- Payment of 0.35 USDC not provided — 402 Payment Required response
- Too many series IDs in a single request may cause timeout or partial results
- Limit parameter set too high may slow response
- FRED upstream outage causes data unavailability
