## Get started in 3 steps

<Steps>
  <Step title="Get your API key">
    Sign up for Stemfard to receive your API key. You'll include this key in the `Authorization` header of every request.
  </Step>

  <Step title="Make your first request">
    Send a POST request to any mathematics endpoint with your matrix data. The API returns results immediately, along with optional step-by-step solutions.
  </Step>

  <Step title="Customize the response">
    Use the `api_level` parameter to control response verbosity — choose `lite` for just the answer, `standard` to include solution steps, or `detailed` for the full educational response.
  </Step>

## What Stemfard offers

Stemfard's API covers a growing library of mathematics operations, starting with comprehensive linear algebra support:

* **Matrix Arithmetic** — Addition, subtraction, element-wise multiplication/division/power, and matrix multiplication
* **Matrix Dimensions** — Query the number of rows, columns, or full shape of any matrix
* **Matrix Statistics** — Compute min, max, sum, mean, median, variance, and standard deviation across rows, columns, or the entire matrix
* **Step-by-step solutions** — Every computation can return a detailed solution in HTML, LaTeX, or speech format
* **Learning pathways** — Related educational endpoints are surfaced alongside results to support deeper exploration

<Note>
  The Stemfard API base URL is `https://api.stemfard.com`. All endpoints use HTTPS and require a valid API key.
