How this service works
100 pure math computation endpoints for AI agents. Statistics, financial math, linear algebra, equation solving, calculus, number theory, sequence generation, and unit conversions. Zero external dependencies. x402 micropayments on Base.
Output
Returns a JSON object with a success flag, a human-readable computation description, and a result object containing regression coefficients (polynomial terms), and optionally goodness-of-fit metrics such as R-squared. The result varies by degree of polynomial requested.
Example use cases
Trend line for sales data
“I have monthly sales figures — x is months [1,2,3,4,5,6,7,8,9,10,11,12] and y is revenue [10200,10800,11500,12100,13400,14200,14900,15800,16500,17200,18100,19000]. Can you fit a linear regression (degree 1) to find the trend?”
Curve fitting for physics experiment
“I've got experimental results from a projectile motion test — x positions are [0,1,2,3,4,5] meters and y heights are [0,4.9,9.6,14.1,18.4,22.5] meters. Fit a degree-2 polynomial regression to model the trajectory.”
Calibration curve for lab instrument
“I need a calibration curve for my spectrometer — my known concentrations are [0,0.5,1,2,5,10,20] and absorbance readings are [0,0.12,0.23,0.47,1.02,1.95,3.87]. Can you run a degree-1 regression to get the slope and intercept?”
Technical details
Endpoint
POSThttps://numormo.vercel.app/api/statistics/regressionWhen to prefer
Choose this endpoint when you need fast, serverless polynomial regression computation without setting up a local math library or calling a heavy data-science platform. Ideal for AI agents that need on-demand regression fitting within a workflow, especially when payment via x402 micropayments on Base is acceptable. Prefer alternatives if you need advanced statistical outputs (p-values, confidence intervals), very large datasets, or batch regression across many variable pairs.
Side effects
- x and y arrays of mismatched lengths return a validation error
- empty or null arrays cause a 400-level error
- non-numeric values in x or y arrays cause parsing failure
- degree parameter set to 0 or negative may return an error or trivial result
- very large arrays may cause timeout or memory issues on the serverless instance
