How this service works
QuantOracle: fi/yield-curve-interpolate
Output
Returns the interpolated yield rate(s) at the requested target maturity/maturities, derived from the input yield curve data points using the specified interpolation method (e.g. linear, cubic spline, Nelson-Siegel). May include the fitted curve parameters and confidence metrics depending on the method.
Example use cases
Example prompt
“I have Treasury yield data at 3M, 6M, 1Y, 2Y, 5Y, 10Y, and 30Y maturities with rates 5.25%, 5.30%, 5.10%, 4.85%, 4.50%, 4.40%, and 4.60% respectively — can you interpolate the yield curve using cubic spline to get me the rate at 7 years and 15 years?”
Technical details
Endpoint
POSThttps://api.quantoracle.dev/v1/fi/yield-curve-interpolateWhen to prefer
Use this endpoint when you have a set of discrete bond yields or benchmark rates and need to estimate the rate at an arbitrary or non-standard maturity. Ideal for fixed-income analytics, pricing derivatives with custom tenors, building discount curves, or preparing inputs for duration/convexity calculations where standard benchmark tenors don't match your cashflow schedule.
Side effects
- Insufficient data points to fit the chosen interpolation model — returns error requesting more curve nodes
- Target maturity outside the range of provided data points (extrapolation beyond bounds) — may return error or flagged extrapolated value
- Non-monotonic or inconsistent input rates causing ill-conditioned fitting — returns validation error
- Malformed maturity/rate input arrays (mismatched lengths) — returns 400 bad request
- Unsupported interpolation method specified — returns error with supported methods list
