Numora Matrix QR Decomposition API
x402
Numora Matrix QR Decomposition API is a paid API for AI agents from numormo.vercel.app, paid per call via x402, $0.1/call, status unknown (last checked 2026-09-13).
Computes the QR decomposition of a given matrix, returning orthogonal (Q) and upper triangular (R) factor matrices.

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' (boolean), 'computation' (human-readable description of what was computed), and 'result' containing the Q (orthogonal) and R (upper triangular) factor matrices as 2D arrays.
Example use cases
Least squares regression computation
“I have a design matrix [[1,2],[3,4],[5,6]] and I want to solve a least squares problem — can you QR-decompose it so I can work with the orthogonal and upper triangular factors?”
Eigenvalue algorithm preprocessing
“Before running an eigenvalue iteration, I need the QR decomposition of [[4, 3], [6, 3]] — can you give me the Q and R matrices?”
Checking numerical stability of a matrix
“Can you QR-decompose my 3x3 matrix [[2,1,0],[1,3,1],[0,1,2]] so I can inspect its orthogonal structure and upper triangular factor?”
Technical details
Endpoint
POSThttps://numormo.vercel.app/api/matrix/qrWhen to prefer
Choose this endpoint when you need a pure, dependency-free QR factorization with no setup overhead and micropayment-based access. Prefer it for lightweight agent workflows needing on-demand matrix decomposition without provisioning a full numerical computing environment.
Side effects
- Non-numeric or malformed matrix elements cause a validation error
- Non-2D array input rejected
- Singular or rank-deficient matrix may produce degenerate Q/R factors
- Missing required field 'A' returns an error
- Very large matrices may time out or hit memory limits on the serverless host
