# Numora Matrix Transpose

> Numora Matrix Transpose is a paid API for AI agents from numorapoi.orbonomy.xyz, paid per call via x402, $0.04/call, status unknown (last checked 2026-09-14).

Computes the transpose of a 2D matrix, flipping rows and columns

## Facts

- Endpoint: POST https://numorapoi.orbonomy.xyz/api/matrix/transpose
- Price: $0.04/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-f66c7641
- Structured record (JSON): https://api.zero.xyz/v1/capabilities/cap_ob8gTJiHf_5cszHRCG3K9

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-f66c7641 -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 flipped.

## When to prefer this

Use this endpoint when you need a lightweight, zero-dependency pure-math matrix transpose computation without setting up a local math library. Ideal for AI agents that need on-demand linear algebra via API with micropayment access (x402/Base). Prefer over general-purpose compute platforms when you want a simple, predictable REST call for a single well-defined matrix operation.

## Known failure modes

- Missing required field 'A': returns error if matrix is not provided
- Non-rectangular matrix (jagged array): may return error or undefined behavior
- Non-2D input (flat array or scalar): returns validation error
- Payment failure via x402 micropayment: returns 402 Payment Required
- Empty matrix input: may return empty result or error

## 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 result object containing the transposed 2D matrix, and a computation string describing what was computed (e.g. 'Transposed a 3x3 matrix').
