Frequently Asked Questions
Everything you need to know about the Mathix API.
Integration is simple. Send requests to the Mathix API using your API key and choose the model that fits your use case. You can build your own interface, connect it to your existing product, and return structured responses in JSON. Our API documentation includes request examples, model details, and implementation guidance to help you get started quickly.
Math models are optimized for solving math problems with step by step explanations and stronger reasoning for calculations, equations, and learning workflows. General models are designed for broader tasks such as coding, writing, summaries, analysis, extraction, and structured text generation. This gives you flexibility to use appropriate API for both specialized math tasks and everyday AI tasks.
The API supports text input and selected workflows can also support image or handwritten input. Responses can be returned as clean JSON, plain text, or LaTeX-friendly output depending on your implementation. This makes it easy to use Mathix in apps, dashboards, internal tools, and automated workflows.
If your product is focused on math solving, start with m-regular-1.0 for strong step by step math reasoning. If you need broader capabilities like coding, writing, or analysis, start with g-regular-1.0. If speed and lower cost matter most, the fast models are a strong starting point for lightweight tasks.
Yes. We take security seriously and use industry-standard protections for API access and data handling. Requests are sent securely, and we focus on building a reliable platform for developers, products, and institutions that need dependable AI infrastructure.
Yes. In addition to math-focused models, Mathix also offers general-purpose models for coding, writing, deep analysis, summaries, and other fast-response workflows. That means you can use one API across multiple product features instead of stitching together separate providers for math and general tasks.
Start by adding a minimum of $5 in API credits. Once your credits are added, you can generate your API key and begin making requests immediately.
