# Numora Matrix SVD (Singular Value Decomposition)

> Numora Matrix SVD (Singular Value Decomposition) is a paid API for AI agents from numormor.netlify.app, paid per call via x402, $0.1/call, status unknown (last checked 2026-09-13).

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

## Facts

- Endpoint: POST https://numormor.netlify.app/api/matrix/svd
- 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-svd-singular-value-decomposition-9fffe4ac
- Structured record (JSON): https://api.zero.xyz/v1/capabilities/cap_9_5Al8ZnGNw8URvNs4-bv

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-singular-value-decomposition-9fffe4ac -d '<json body>'
```

Example prompt: Compute the singular value decomposition of this matrix: [[1, 2, 3], [4, 5, 6], [7, 8, 9]] — I need the U, Sigma, and V-transpose components.

## When to prefer this

Use this endpoint when you need a pure-math, zero-dependency SVD computation on demand without setting up a local linear algebra library. Ideal for AI agents performing dimensionality reduction, PCA preprocessing, least-squares solutions, or matrix rank analysis using x402 micropayments on Base with no infrastructure overhead.

## Known failure modes

- Non-numeric matrix entries — returns error or unexpected result
- Non-rectangular or jagged array (rows of unequal length) — may fail validation
- Empty matrix provided — likely returns error
- Singular or near-singular matrix — may still succeed but with near-zero singular values
- Malformed JSON body — HTTP 400 bad request
- Payment not provided or insufficient — HTTP 402 payment required

## 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 human-readable computation description, and a result object containing the SVD components: U (left singular vectors), Sigma (singular values), and V^T (right singular vectors transposed).
