# Numora Matrix Eigenvalue Computation

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

## Facts

- Endpoint: POST https://numormor.netlify.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-eigenvalue-computation-5fdbe09a
- Structured record (JSON): https://api.zero.xyz/v1/capabilities/cap_t-_wruIKagZ0SSTskhrO7

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-eigenvalue-computation-5fdbe09a -d '<json body>'
```

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

## When to prefer this

Choose this endpoint when you need server-side, dependency-free eigenvalue computation for a square matrix, especially in agentic workflows where you want to pay per-call via x402 micropayments on Base rather than bundling a math library. Ideal for lightweight AI agent pipelines doing linear algebra, PCA prep, or stability analysis.

## Known failure modes

- Non-square matrix provided — eigenvalues are undefined, likely returns error
- Missing required field 'A' — returns validation error
- Malformed 2D array input — parsing error returned
- Payment not attached or insufficient — x402 payment required error
- Non-numeric values in matrix — computation failure or NaN result

## 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 flag, a result object containing the computed eigenvalues of the input matrix, and a human-readable string describing what was computed.
