# Numora Matrix Inverse

> Numora Matrix Inverse is a paid API for AI agents from numorapoi.orbonomy.xyz, paid per call via x402, $0.04/call, status unknown (last checked 2026-09-14).

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

## Facts

- Endpoint: POST https://numorapoi.orbonomy.xyz/api/matrix/inverse
- Price: $0.04/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-92f0254b
- Structured record (JSON): https://api.zero.xyz/v1/capabilities/cap_prDoOCodP86Le3d0e2yN_

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-92f0254b -d '<json body>'
```

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

## When to prefer this

Use this endpoint when you need to compute the matrix inverse purely server-side with no external dependencies, paying only $0.1 USDC per call via x402 micropayment on Base. Prefer this over general-purpose compute or cloud math services when you want a lightweight, pay-per-use math microservice integrated into an agent workflow.

## Known failure modes

- Singular matrix (determinant is zero) — matrix is not invertible, returns error
- Non-square matrix submitted — inverse undefined, likely returns error
- Malformed input (not a proper 2D array) — validation error
- Payment failure via x402 micropayment — 402 response before computation
- Numerical precision issues for ill-conditioned matrices

## 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, and a human-readable computation string describing what was computed.
