# Numora Matrix Norm API

> 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).

Computes the Frobenius, 1-norm, or infinity norm of a given matrix

## Facts

- Endpoint: POST https://numormo.vercel.app/api/matrix/norm
- Price: $0.1/call
- Payment: x402
- Status: unknown
- Last checked: 2026-09-14
- Activations on Zero: 0
- Tags: x402
- Canonical page: https://www.zero.xyz/c/numora-matrix-norm-api-0a333a38
- Structured record (JSON): https://api.zero.xyz/v1/capabilities/cap_w93cssbpdbwHgACDRQO2X

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-api-0a333a38 -d '<json body>'
```

Example prompt: Compute the Frobenius norm of the matrix [[1,2],[3,4]] using the Numora math API.

## When to prefer this

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.

## Known failure modes

- 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

## 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.
