# Numora Matrix Eigenvalues API

> Numora Matrix Eigenvalues 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 of a given square matrix using pure server-side math with no external dependencies.

## Facts

- Endpoint: POST https://numormo.vercel.app/api/matrix/eigenvalues
- 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-eigenvalues-api-720c774c
- Structured record (JSON): https://api.zero.xyz/v1/capabilities/cap_wbdqI4kejUFVNsl4rboU5

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-eigenvalues-api-720c774c -d '<json body>'
```

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

## When to prefer this

Choose this endpoint when you need a lightweight, dependency-free eigenvalue computation callable from any AI agent or serverless environment without installing scientific Python libraries. Ideal for single-shot computations billed per-use via x402 micropayments on Base, where you want deterministic pure-math results without spinning up a data science stack.

## Known failure modes

- Non-square matrix provided — eigenvalues are only defined for square matrices
- Matrix contains non-numeric values — computation will fail
- Empty or malformed 2D array input — validation error returned
- Numerical instability for ill-conditioned matrices may produce approximate results
- Payment failure via x402 micropayment protocol — call not executed

## 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 boolean 'success' field, a 'result' object containing the computed eigenvalues (real and/or complex), and a 'computation' string providing a human-readable description of what was calculated.
