# Numora Matrix Inverse

> Numora Matrix Inverse 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 inverse of a square matrix using pure math with no external dependencies

## Facts

- Endpoint: POST https://numormo.vercel.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-60b4812c
- Structured record (JSON): https://api.zero.xyz/v1/capabilities/cap_DCJlDMJnmAIWARNMebXoQ

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-60b4812c -d '<json body>'
```

Example prompt: Can you compute the inverse of this matrix: [[4, 7], [2, 6]]?

## When to prefer this

Choose this endpoint when you need a fast, self-contained matrix inverse computation with no external dependencies, especially in agentic workflows where accuracy matters and you want to avoid importing heavy math libraries. Ideal for AI agents doing linear algebra as part of larger calculations (solving linear systems, portfolio optimization, ML operations) via simple micropayment-based API calls on Base.

## Known failure modes

- Singular or non-invertible matrix returns an error (determinant is zero)
- Non-square matrix input causes a validation error
- Malformed 2D array (jagged rows) may return a parsing error
- Payment failure via x402 returns 402 status before computation begins

## 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 (e.g. 'Computed inverse of 3x3 matrix').
