One x402 call (no parameters) returns the yield curve (the 2s10s and 3m10y spreads, inversion status, steepening vs flattening trend, and a recession flag off the NY Fed's 3m10y), credit spreads (ICE BofA investment-grade and high-yield option-adjusted spreads, each scored against its own 1-year history so 'HY at the 8th percentile' reads as calm vs stressed, plus week-over-week widening), real yields and 10-year inflation breakevens, and a combined rates-regime read (expansion / late_cycle / credit_stress / mixed).
