# Numora Matrix Norm Computation

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

Computes the norm of a matrix (e.g. Frobenius, spectral, or other norm types) given a 2D array input

## Facts

- Endpoint: POST https://numormor.netlify.app/api/matrix/norm
- Price: $0.1/call
- Payment: x402

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability numora-matrix-norm-computation-c3b27c4b -d '<json body>'
```

Example prompt: Can you compute the Frobenius norm of this matrix: [[1, 2, 3], [4, 5, 6], [7, 8, 9]]?

## When to prefer this

Use this endpoint when you need a pure mathematical computation of a matrix norm with no external dependencies, especially in automated agent workflows requiring linear algebra operations. Ideal for numerical analysis, machine learning preprocessing, and scientific computing where reliability and determinism are essential.

## Known failure modes

- Missing required 'A' field returns validation error
- Non-2D array input causes computation failure
- Invalid norm type string returns error
- Non-numeric matrix entries cause failure
- Payment not attached or insufficient USDC causes 402 response

## 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 flag, a result object containing the computed norm value, and a human-readable computation description string explaining what was calculated.
