# Numora Matrix Inverse API

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

Computes the inverse of a square matrix using pure math computation with no external dependencies

## Facts

- Endpoint: POST https://numomo.vercel.app/api/matrix/inverse
- Price: $0.1/call
- Payment: x402
- Status: unknown
- Last checked: 2026-09-13

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-api-57bfc4cf -d '<json body>'
```

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

## When to prefer this

Choose this endpoint when you need precise, pure-math matrix inversion without relying on external libraries or cloud ML services. Ideal for AI agents needing lightweight, micropayment-based math computation on-demand, especially in financial modeling, robotics, or scientific workflows where correctness and minimal dependencies are critical.

## Known failure modes

- Non-square matrix input — matrix must be square to have an inverse
- Singular matrix (determinant = 0) — non-invertible matrices return an error
- Malformed input array — A must be a valid 2D array of numbers
- Missing required field A — request fails with 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 'success' boolean, a 'result' object containing the inverse matrix as a 2D array, and a 'computation' string describing what was computed in human-readable form.
