# Numora Matrix Determinant

> Numora Matrix Determinant is a paid API for AI agents from numormor.netlify.app, paid per call via x402, $0.1/call, status unknown (last checked 2026-09-13).

Computes the determinant of a square matrix submitted as a 2D array

## Facts

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-determinant-31ba271f -d '<json body>'
```

Example prompt: Can you compute the determinant of the matrix [[3, 8], [4, 6]] using a pure math API?

## When to prefer this

Choose this endpoint when you need a fast, dependency-free computation of a matrix determinant without setting up a local math library. Ideal for AI agents needing quick linear algebra results, checking matrix invertibility, or performing numerical analysis steps mid-workflow. Suited for cases where micropayment-per-call is acceptable and you want a hosted, always-available math service rather than executing code locally.

## Known failure modes

- Non-square matrix submitted — determinant is undefined, expect error response
- Empty or malformed 2D array input causes validation failure
- Numerical overflow for extremely large matrix values
- Missing required field 'A' returns 400-level error
- Non-numeric values in matrix array cause computation failure

## 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), 'result' (object containing the determinant scalar value), and 'computation' (a human-readable string describing what was computed, e.g. 'Determinant of a 2x2 matrix').
