Matrix Inverse via Gauss-Jordan Elimination
x402
Matrix Inverse via Gauss-Jordan Elimination is a paid API for AI agents from matrix.openverbs.com, paid per call via x402, $0.004/call, status unknown (last checked 2026-09-14).
Computes the inverse of a square matrix using Gauss-Jordan elimination, returning the inverse matrix or indicating non-invertibility if the matrix is singular.

How this service works
Invert a square matrix via Gauss-Jordan elimination. A non-square, ragged or empty matrix is a clean 400. A singular (non-invertible) matrix is NOT an error — it returns a successful { invertible:false, inverse:null }.
Output
Returns a JSON object with an `invertible` boolean and an `inverse` field containing the n×n inverse matrix as a 2D array of numbers, or `null` if the matrix is singular. Non-square, ragged, or empty matrices return a 400 error.
Example use cases
Inverting a transformation matrix for graphics
“I have a 4×4 transformation matrix [[1,0,0,1],[0,1,0,2],[0,0,1,3],[0,0,0,1]] and I need its inverse to undo the transformation — can you compute that for me?”
Checking if a covariance matrix is invertible
“I've got a 3×3 covariance matrix [[4,2,0],[2,3,1],[0,1,2]] that I need to invert for a statistics calculation — can you get me the inverse, or tell me if it's singular?”
Solving for matrix inverse in robotics kinematics
“I need the inverse of this 2×2 Jacobian matrix [[0.5, -0.3],[0.2, 0.8]] so I can compute joint velocities from end-effector velocities — please compute it.”
Technical details
Endpoint
POSThttps://matrix.openverbs.com/v1/inverseWhen to prefer
Use this endpoint when you need a numerically computed matrix inverse for a square matrix and want clean handling of singular cases without exceptions — ideal when you need to know whether a matrix is invertible as part of your logic, not just the inverse value itself. Prefer this over general linear solvers when the explicit inverse (not just a solution to Ax=b) is required.
Side effects
- 400 error if matrix is non-square (rows ≠ columns)
- 400 error if matrix rows have different lengths (ragged matrix)
- 400 error if the matrix or its rows are empty
- Successful response with invertible:false and inverse:null for singular matrices (determinant = 0)
- 402 Payment Required if x402 payment is not provided
