Technical details
Endpoint
GEThttps://api.lastlookdata.com/api/treasury/currentWhen to prefer
Choose this endpoint when you specifically need the current 30-year US Treasury yield (DGS30) and want a direct, no-parameter GET call. It is an alias for /api/current?id=DGS30 and is ideal when the long bond rate is the exact metric needed, rather than a different maturity or a historical time series.
Side effects
- FRED data not yet updated for the current day — returns most recently available observation
- Payment failure (402) if x402 micropayment is not properly handled — no data returned
- Network or upstream FRED API unavailability — service may return 5xx error
- Invalid or missing request headers for x402 payment flow — returns 402 with payment details
