How this service works

QuantOracle: macro/real-yield

Output

Returns the computed real yield (simple subtraction), the Fisher-equation-adjusted real yield percentage, the breakeven inflation rate, and echoes back the input tenor and nominal yield — all returned in under 20ms.

Example use cases

Example prompt

“What's the real yield on a 10-year bond with a 4.5% nominal yield and 2.3% inflation expectation? Give me both the simple and Fisher equation results.”

When to prefer

Use this endpoint when you need fast, precise real yield decomposition for macro analysis, fixed income research, or portfolio construction — especially when you need both simple real yield and the more precise Fisher equation adjustment in a single call. Prefer this over manual calculation when accuracy and speed matter at scale.

Side effects

Missing required fields (tenor_years, nominal_yield, or inflation_expectation) returns a 400 error
Non-numeric or out-of-range values for yield inputs may return a validation error
Negative nominal yields or extreme inflation values may produce unexpected or economically nonsensical results
Payment failure or insufficient USDC balance returns a 402 Payment Required error
