# ApexAPI Matrix Math Operations

> ApexAPI Matrix Math Operations is a paid API for AI agents from apex-api-gamma.vercel.app, paid per call via x402, $0.158326/call, status unknown (last checked 2026-09-15).

Performs matrix operations and computations via a paid per-call API endpoint using USDC on Base

## Facts

- Endpoint: POST https://apex-api-gamma.vercel.app/api/tools/math/matrix
- Price: $0.158326/call
- Payment: x402
- Status: unknown
- Last checked: 2026-09-15
- Activations on Zero: 0
- Tags: x402
- Canonical page: https://www.zero.xyz/c/apexapi-matrix-math-operations-80a8ebd2
- Structured record (JSON): https://api.zero.xyz/v1/capabilities/cap_xk0fgqGT_LzIaHYxfFzCZ

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 apexapi-matrix-math-operations-80a8ebd2 -d '<json body>'
```

Example prompt: Can you multiply these two matrices together for me: [[1,2],[3,4]] times [[5,6],[7,8]]?

## When to prefer this

Use this endpoint when you need programmatic matrix math operations — multiplication, inversion, determinants, eigenvalues, or linear system solving — without setting up a dedicated math library or local compute environment, and you are already operating within a pay-per-call USDC on Base payment flow.

## Known failure modes

- Invalid matrix dimensions causing operation failure
- Malformed query string not recognized as a valid matrix operation
- Singular matrix errors when inversion is requested
- Payment failure if insufficient USDC balance on Base
- Timeout for very large matrix computations
- Unsupported operation type returns error response

## 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 products, inverses, determinants, eigenvalues, or other linear algebra outputs depending on the query provided.
