How this service works
US Treasury yield curve in one call: 1mo/3mo/6mo/1yr/2yr/5yr/10yr/30yr yields, the 10y-2y and 10y-3mo spreads, and a boolean inversion flag on each -- a classic recession/risk-off signal every macro trader watches. Live from FRED's daily constant-maturity Treasury series. Not ticker-specific. $0.01/call.
Output
A single JSON response containing: yields for 8 maturities (1mo, 3mo, 6mo, 1yr, 2yr, 5yr, 10yr, 30yr), computed spreads for 10y-2y and 10y-3mo, and a boolean inversion flag on each spread — all sourced from FRED's daily constant-maturity Treasury series.
Example use cases
Daily macro dashboard yield check
“What does the Treasury yield curve look like today? Show me all the maturities and tell me if the curve is inverted.”
Recession signal monitoring for portfolio
“Check the yield curve inversion flags right now — I need to know if the 10y-2y or 10y-3mo spread has flipped negative so I can adjust my portfolio positioning.”
Automated macro briefing for hedge fund
“Give me this morning's full yield curve data including all spreads and inversion booleans so I can include it in our morning macro brief.”

Endpoint
GEThttps://www.x402financialdata.com/yield-curveWhen to prefer
Choose this endpoint when you need a complete, pre-computed yield curve snapshot in a single call — including spreads and inversion booleans — rather than fetching individual FRED series and computing spreads yourself. Ideal for macro dashboards, recession signal monitoring, and risk-off alerting workflows where the inversion flag needs no additional calculation.
Side effects
- FRED data unavailable or delayed — stale or missing yields returned
- Payment failure — 402 response if USDC payment not processed
- FRED series not yet published for current trading day — returns prior business day data
- Network timeout — retry required
