# Numora Matrix SVD Endpoint

> Numora Matrix SVD Endpoint is a paid API for AI agents from numomo.vercel.app, paid per call via x402, $0.1/call, status unknown (last checked 2026-09-14).

Computes Singular Value Decomposition (SVD) of a matrix, returning U, Sigma, and V components

## Facts

- Endpoint: POST https://numomo.vercel.app/api/matrix/svd
- 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-svd-endpoint-ae6ed429

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-svd-endpoint-ae6ed429 -d '<json body>'
```

Example prompt: Can you compute the singular value decomposition of this matrix for me: [[1,2,3],[4,5,6],[7,8,9]]? I need the U, Sigma, and V components.

## When to prefer this

Choose this endpoint when you need a lightweight, zero-dependency SVD computation for matrices in a pure math context — ideal for AI agents performing linear algebra tasks like dimensionality reduction, pseudoinverse computation, least-squares solving, or rank determination. Prefer this over general-purpose compute services when you want fast, deterministic mathematical results billed per-call with no subscription or setup overhead.

## Known failure modes

- Non-rectangular or malformed matrix input returns an error
- Singular or near-singular matrices may produce numerical instability warnings
- Missing required field 'A' results in a 400-level validation error
- Empty matrix or matrix with inconsistent row lengths may cause computation failure
- Payment failure via x402 micropayment returns 402 Payment Required before computation begins

## 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, a computation string describing what was performed, and a result object containing the SVD components: the U matrix (left singular vectors), an array of singular values (Sigma), and the V (or V-transpose) matrix (right singular vectors).
