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

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 a boolean 'success' field, a 'result' object containing the computed norm value, and a 'computation' string describing what was calculated in human-readable form.
Example use cases
Numerical stability check before solving
“Before I solve this linear system, compute the infinity norm of the coefficient matrix [[4,-1,0],[-1,4,-1],[0,-1,4]] so I can estimate its condition number.”
ML weight matrix magnitude check
“I have a neural network weight matrix [[0.5,0.3,-0.1],[0.2,-0.4,0.6]] — can you compute its Frobenius norm so I can see how large the weights have grown during training?”
Control system matrix analysis
“For my control system analysis, calculate the 1-norm of the state transition matrix [[2,0,-1],[1,3,0],[0,-2,1]] to check for stability bounds.”
Technical details
Endpoint
POSThttps://numormo.vercel.app/api/matrix/normWhen to prefer
Choose this endpoint when you need a fast, dependency-free computation of a standard matrix norm (Frobenius, 1-norm, or infinity norm) without standing up any numerical library infrastructure. Ideal for AI agents performing on-the-fly linear algebra checks — e.g., assessing matrix magnitude, conditioning, or weight growth — where micropayment-per-call pricing is preferable to managing a math library deployment.
Side effects
- Non-rectangular or jagged 2D array causes validation error
- Unsupported norm type string outside enum ['frobenius','1','inf'] returns error
- Empty or null matrix A returns 400-level error
- Non-numeric matrix elements cause computation failure
- Missing required field A returns schema validation error
