# Numora Matrix Eigenvectors

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

## Facts

- Endpoint: POST https://numormor.netlify.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-a64b3697
- Structured record (JSON): https://api.zero.xyz/v1/capabilities/cap_dZzOtBj-C9KUKyofnpRCe

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-a64b3697 -d '<json body>'
```

Example prompt: Can you compute the eigenvalues and eigenvectors of this matrix: [[4, 1], [2, 3]]?

## When to prefer this

Choose this endpoint when you need server-side, dependency-free eigenvalue/eigenvector computation as part of an automated agent workflow, especially when you want a pay-per-call model without setting up a full numerical library. Ideal for agents that need linear algebra primitives without executing local code.

## Known failure modes

- Non-square matrix provided — eigenvectors undefined, returns error
- Matrix contains non-numeric values — computation fails
- Empty or malformed 2D array input — schema validation error
- Matrix is singular or ill-conditioned — numerical instability may produce inaccurate results
- Payment not included or insufficient — x402 payment required 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 eigenvalues and eigenvectors arrays, and a 'computation' string describing what was computed in human-readable form.
