# Numora Matrix Eigenvectors API

> Numora Matrix Eigenvectors API 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 eigenvalues and eigenvectors of a given square matrix using pure server-side math with no external dependencies.

## Facts

- Endpoint: POST https://numormo.vercel.app/api/matrix/eigenvectors
- 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-eigenvectors-api-9db4833b
- Structured record (JSON): https://api.zero.xyz/v1/capabilities/cap_VBLwyD84mdTwTzZt_ct4n

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-eigenvectors-api-9db4833b -d '<json body>'
```

Example prompt: Calculate the eigenvalues and eigenvectors of this matrix: [[4, 1], [2, 3]] — I need the full spectral decomposition.

## When to prefer this

Choose this endpoint when you need a lightweight, serverless, zero-dependency pure math computation of eigenvalues and eigenvectors, especially inside AI agent pipelines that support x402 micropayments on Base. Prefer it over heavier numerical libraries when you need a simple HTTP call without spinning up a Python/NumPy environment.

## Known failure modes

- Non-square matrix provided — returns error since eigendecomposition requires square input
- Matrix contains non-numeric values — parsing error returned
- Singular or defective matrix may yield complex eigenvalues not representable in real form
- Missing required field 'A' — returns validation error
- Payment not fulfilled via x402 micropayment — request rejected before computation

## 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' (containing eigenvalues as an array and eigenvectors as a 2D array or list of vectors), and 'computation' (a human-readable string describing what was computed).
