API Documentation | Mars The Limit

Posted on March 1, 2026 by Boden Bensema

Welcome to the Mars the Limit API. This site includes a collection of API tools I've made that I found useful when working on my projects at home and for school. These APIs are designed to save time and simplify calculations for students, engineers, builders, and developers of all experience levels.

Authentication

All API requests require an API key for authentication. Include it in the request header as follows:

1Authentication: Bearer YOUR_API_KEY_HERE

Your API key can be found in the dashboard under the "API & Keys" tab. Keep your key secret. Do not expose it in public code.

Base URL

The base URL for all APIs is https://api.marsthelimit.com.

Example with cURL

1curl -X POST https://api.marsthelimit.com/calculate \ 2 -H "Content-Type: application/json" \ 3 -H "Authentication: Bearer YOUR_API_KEY_HERE" \ 4 -d '{"law":"ohms","vars":{"V":12,"R":6}}'

General API Usage

All endpoints accept a JSON payload. The structure for each API is different and can be found in each API's documentation.
