# Numora Matrix Inverse

> Numora Matrix Inverse 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 multiplicative inverse of a square matrix using pure math, returning the inverse matrix and a human-readable computation description.

## Facts

- Endpoint: POST https://numormor.netlify.app/api/matrix/inverse
- 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-inverse-a969a9dc
- Structured record (JSON): https://api.zero.xyz/v1/capabilities/cap_ogjJAzzv7uk4R-ztQebys

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-inverse-a969a9dc -d '<json body>'
```

Example prompt: Can you compute the inverse of this matrix for me: [[2, 1], [5, 3]]?

## When to prefer this

Use this endpoint when you need to compute the exact inverse of a square matrix server-side without relying on local numerical libraries. Ideal for AI agents that lack native linear algebra support or need a zero-dependency, pay-per-call computation with transparent pricing via x402 micropayments on Base.

## Known failure modes

- Matrix is singular (determinant is zero) — no inverse exists, endpoint returns error
- Non-square matrix provided — inverse is undefined
- Malformed input: A is not a valid 2D array
- Numerical instability for near-singular matrices — result may have large floating-point errors
- Missing required field A returns validation error
- Payment failure (x402) if USDC balance insufficient

## 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=true, a result object containing the inverse matrix (as a 2D array of floats), and a computation string describing what was computed in human-readable form.
