# Numora Matrix SVD (Singular Value Decomposition)

> Numora Matrix SVD (Singular Value Decomposition) 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 Singular Value Decomposition (SVD) of a matrix, returning U, Σ, and V matrices

## Facts

- Endpoint: POST https://numormo.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-singular-value-decomposition-19ae072f
- Structured record (JSON): https://api.zero.xyz/v1/capabilities/cap_HKVzpjdza22AT697lv3CS

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-19ae072f -d '<json body>'
```

Example prompt: Can you compute the singular value decomposition of this matrix: [[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 pure math, dependency-free SVD computation accessible via a simple API call with micropayment billing. Ideal for AI agents needing on-demand matrix factorization without spinning up a numerical computing environment (e.g. NumPy/SciPy). Prefer this over local computation when your agent runtime lacks math libraries, or when you want a consistent, auditable computation with per-call pricing at $0.10 USDC.

## Known failure modes

- Non-numeric matrix values cause a 400 or computation error
- Non-rectangular matrix (jagged array) causes validation failure
- Empty matrix or missing 'A' field returns error
- Extremely large matrices may time out or exceed payload limits
- Singular or near-singular matrices may return near-zero singular values with floating-point imprecision
- Payment failure via x402 returns 402 status 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 human-readable computation description, and a result object containing the U matrix (left singular vectors), an array of singular values (sigma/Σ), and the V or V-transpose matrix (right singular vectors), enabling reconstruction or analysis of the original matrix.
