Getting Started

Introduction

Axion AI is a unified model routing gateway that lets you access 30+ frontier AI models through a single, OpenAI-compatible API endpoint.

✓

Axion is fully compatible with the OpenAI SDK. If you already use OpenAI, switching takes one line of code.

What is Axion?

Axion acts as an intelligent proxy between your application and every major AI provider — OpenAI, Anthropic, Meta, DeepSeek, Mistral, NVIDIA, and more. Instead of managing multiple API keys, SDKs, and billing accounts, you get one key, one endpoint, and one credit balance.

Every request is billed in credits. 1 credit = $0.001. Each model has a transparent per-1K-token rate so you always know what you're spending before you send a request.

Key Concepts

API Key

Your unique credential. Generated in the dashboard. Passed as a Bearer token.

Credits

The billing unit. 1 credit = $0.001. Deducted per request based on token usage.

Model ID

A namespaced string like openai/gpt-4o or anthropic/claude-sonnet-4. Used in the model field.

Endpoint

A single base URL — your domain + /v1 — that handles all model requests.

Base URL

text

https://app.axion.mikedev.site/v1

All API requests are made to this base URL. The path structure mirrors the OpenAI API, so any OpenAI-compatible client works out of the box.
