# Numora Matrix Eigenvalues Computation

> Numora Matrix Eigenvalues Computation is a paid API for AI agents from numomo.vercel.app, paid per call via x402, $0.1/call, status unknown (last checked 2026-09-13).

Computes eigenvalues of a square matrix using pure math, returning all eigenvalues with no external dependencies.

## Facts

- Endpoint: POST https://numomo.vercel.app/api/matrix/eigenvalues
- Price: $0.1/call
- Payment: x402
- Status: unknown
- Last checked: 2026-09-13
- Activations on Zero: 0
- Tags: x402
- Canonical page: https://www.zero.xyz/c/numora-matrix-eigenvalues-computation-723496af

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-computation-723496af -d '<json body>'
```

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

## When to prefer this

Use this endpoint when you need fast, dependency-free eigenvalue computation on Base with x402 micropayments, especially for AI agents that need deterministic math results without standing up a numerical computing environment. Prefer this over general-purpose code execution when you want a single, focused matrix eigenvalue call with predictable cost ($0.1 USDC) and no server-side library provisioning.

## Known failure modes

- Non-square matrix input returns an error — eigenvalues are only defined for square matrices
- Singular or ill-conditioned matrices may yield numerically unstable results
- Missing or malformed 'A' field in request body returns a validation error
- Non-numeric values inside the matrix array cause a parse/computation failure

## 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), 'result' containing the computed eigenvalues (real and/or complex), and 'computation' with a human-readable description of what was computed.
