# Numora Matrix Transpose API

> Numora Matrix Transpose API 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 transpose of a 2D matrix, flipping rows and columns, with no external dependencies.

## Facts

- Endpoint: POST https://numormo.vercel.app/api/matrix/transpose
- 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-transpose-api-8bd8737d

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-transpose-api-8bd8737d -d '<json body>'
```

Example prompt: Transpose this matrix for me: [[1, 2, 3], [4, 5, 6], [7, 8, 9]] — I need the rows and columns swapped so I can use it in my next calculation.

## When to prefer this

Choose this endpoint when you need a fast, dependency-free matrix transpose computation without setting up a full numerical library. Ideal for AI agents performing linear algebra as a sub-step in larger workflows (e.g., preparing matrices for multiplication, solving linear systems) where a lightweight, pay-per-call approach via x402 micropayments is preferred over bundling heavy math libraries.

## Known failure modes

- Missing required field 'A' — returns error if matrix is not provided
- Non-rectangular or malformed 2D array — may return error or unexpected result
- Empty matrix input — behavior may vary
- Non-numeric values in matrix — computation may fail or produce unexpected output

## 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' (boolean, always true on success), 'result' (an object containing the transposed 2D matrix with rows and columns swapped), and 'computation' (a human-readable string describing what was computed).
