Endpoint
POSThttps://fredthom.vercel.app/api/latestWhen to prefer

Side effects
- Invalid or nonexistent FRED series ID returns an error or empty result
- Missing required seriesId field causes a 400-level error
- FRED upstream outage may cause delayed or failed responses
- Series with no recent data may return an empty latest object
- Payment not completed (x402) results in 402 Payment Required before data is returned
