Getting Started with TokenFast

Welcome to TokenFast! This guide will walk you through everything you need to start making API calls to the world's best AI models in under five minutes.

Step 1: Create Your Account

Head to tokenfast.ai and sign up with your email or GitHub account. No credit card is required to create an account.

Step 2: Generate an API Key

Once logged in, navigate to your Dashboard and click Create New Key. Your key will look something like:

sk-akh-xxxxxxxxxxxxxxxxxxxx

Copy it somewhere safe — for security, we only show the full key once.

Step 3: Make Your First Request

TokenFast is fully compatible with the OpenAI SDK. Here's how to call Claude using the OpenAI Python library:

from openai import OpenAI

client = OpenAI(
    api_key="sk-akh-your-key-here",
    base_url="https://api.tokenfast.ai/v1",
)

response = client.chat.completions.create(
    model="claude-4-6-sonnet",
    messages=[
        {"role": "user", "content": "Explain quantum computing in one paragraph."}
    ],
)

print(response.choices[0].message.content)

Or with Node.js:

import OpenAI from "openai";

const client = new OpenAI({
  apiKey: "sk-akh-your-key-here",
  baseURL: "https://api.tokenfast.ai/v1",
});

const response = await client.chat.completions.create({
  model: "gpt-4o",
  messages: [
    { role: "user", content: "Write a haiku about programming." },
  ],
});

console.log(response.choices[0].message.content);

Step 4: Monitor Your Usage

Visit the Analytics section in your dashboard to see real-time token consumption, cost breakdowns by model, and request history. Set up budget alerts to stay in control of your spending.
