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
A JSON object containing a 'result' object with the computed derivative value, a 'computation' string describing what was calculated in human-readable form, and a 'success' boolean confirming the computation completed without error.
Example use cases
Example prompt
“Calculate the second-order derivative of x^3 + 2*x^2 - 5 at x = 3 using a step size of 0.001.”
Technical details
Endpoint
POSThttps://numormor.netlify.app/api/calculus/derivativeWhen to prefer
Use this endpoint when you need fast, on-demand numerical differentiation of a mathematical function at a specific point, especially when no symbolic math library is available or when you want a zero-dependency cloud computation. Ideal for AI agents performing calculus tasks, scientific computing pipelines, or educational math tools that need derivative values without setting up local math environments.
Side effects
- Invalid or unparseable function expression returns an error
- Non-numeric x value causes a 400-level validation error
- Order parameter must be a positive integer; non-integer or zero values may fail
- Step size h too small (floating point underflow) or too large (inaccurate approximation) may yield poor results
- Payment not included or insufficient USDC causes 402 Payment Required response
