Numora Matrix Rank API
x402
Numora Matrix Rank API is a paid API for AI agents from numomo.vercel.app, paid per call via x402, $0.1/call, status unknown (last checked 2026-09-14).

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 on success), 'result' (an object containing the computed rank value), and 'computation' (a human-readable string describing what was computed, e.g. 'Rank of a 3x3 matrix').
Example use cases
Check if system of equations is solvable
“I have this coefficient matrix [[2, 1, -1], [4, 2, -2], [6, 3, -3]] — can you compute its rank so I can figure out whether my linear system has a unique solution?”
Verify matrix is full rank before inversion
“Before I try to invert my matrix [[3, 1], [6, 2]], can you compute its rank to check if it's invertible?”
Dimensionality analysis for data science
“I have a feature matrix [[1, 0, 1], [0, 1, 0], [1, 1, 1], [2, 1, 2]] and I need to know its rank to understand the true dimensionality of my data.”
Technical details
Endpoint
POSThttps://numomo.vercel.app/api/matrix/rankWhen to prefer
Choose this endpoint when you need a pure, dependency-free computation of matrix rank with no external library setup, especially within an AI agent workflow that supports x402 micropayments on Base. Ideal when you need a quick, on-demand scalar rank value without spinning up a local numerical computing environment like NumPy or MATLAB.
Side effects
- Non-square or malformed 2D array may return an error
- Missing required 'A' field returns validation error
- Passing a 1D array instead of a 2D array causes failure
- Empty matrix array returns an error
- Non-numeric values in the matrix cause computation failure
