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 success=true, a result object containing identified extrema points (x-coordinates and corresponding function values, classified as minima or maxima), and a human-readable computation string describing what was computed.
Example use cases
Example prompt
“Find all the extrema — both local minima and maxima — of the function f(x) = x^3 - 6x^2 + 9x + 1 on the interval from 0 to 5.”
Technical details
Endpoint
POSThttps://numormor.netlify.app/api/calculus/extremaWhen to prefer
Use this endpoint when you need to find minima and/or maxima of a mathematical function over a bounded interval without any external library dependencies. Ideal for optimization problems in pure math contexts, financial modeling (e.g. profit/cost function peaks), or physics simulations where you need exact extrema locations. Prefer this over general-purpose CAS tools when lightweight, cost-effective micropayment-based computation is acceptable.
Side effects
- Invalid or unparseable function expression — returns error describing parse failure
- Bounds array missing or malformed (not a two-element numeric array) — returns validation error
- Function has no extrema on the given interval (e.g. monotone function) — returns empty extrema list
- Division by zero or undefined values within the interval — returns computation error
- Numerical method fails to converge — returns error with method-specific message
