# NexusAPI Matrix Math Endpoint

> NexusAPI Matrix Math Endpoint is a paid API for AI agents from nexus-api-virid.vercel.app, paid per call via x402, $0.037879/call, status unknown (last checked 2026-09-15).

Performs matrix operations and linear algebra computations via a paid per-call API on Base

## Facts

- Endpoint: POST https://nexus-api-virid.vercel.app/api/tools/math/matrix
- Price: $0.037879/call
- Payment: x402
- Status: unknown
- Last checked: 2026-09-15
- Activations on Zero: 0
- Tags: x402
- Canonical page: https://www.zero.xyz/c/nexusapi-matrix-math-endpoint-6aede172
- Structured record (JSON): https://api.zero.xyz/v1/capabilities/cap_Q8ETpxuoXIkNTMTqAyqAw

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 nexusapi-matrix-math-endpoint-6aede172 -d '<json body>'
```

Example prompt: Can you multiply matrix A [[1,2],[3,4]] by matrix B [[5,6],[7,8]] and give me the result?

## When to prefer this

Choose this endpoint when an AI agent needs on-demand matrix or linear algebra computation without setting up a local math library, and is already operating in a pay-per-call USDC on Base environment. Best for agents that need occasional matrix math as part of a larger workflow rather than heavy batch numerical processing.

## Known failure modes

- Malformed or ambiguous query string may return an error or unexpected result
- Non-square matrix passed to operations requiring square matrices (e.g. inversion, determinant)
- Singular matrix passed to inversion operation causing a mathematical error
- Payment of 0.037879 USDC not received resulting in HTTP 402 rejection
- Overly complex or large matrices may timeout or exceed compute limits

## How this service works

Crypto, AI, Social Media, Finance, Weather, Tools &amp; more. Pay per call in USDC on Base. No API keys.

## Output

Returns computed matrix operation results such as product matrices, determinants, inverses, transposes, or other linear algebra outputs depending on the query provided
