Quickstart

Get from signup to your first API call in under 5 minutes.

TensorX was formerly Tensorix. Existing API endpoints, keys and links keep working and redirect automatically to their tensorx.ai equivalents — there is nothing you need to change.

Step 1: Create Your Account

Go to app.tensorx.ai/register
Enter your email and password
Check your inbox for a verification email
Click the verification link

Step 2: Generate an API Key

Go to your Dashboard
Navigate to API Keys
Click Generate New Key
Enter a name (e.g., "My First Key")
Click Create

Copy your key immediately! The full API key is only shown once. Store it somewhere safe.

Step 3: Make Your First API Call

Test that everything works with a simple curl command:

curl https://api.tensorx.ai/v1/models \
  -H "Authorization: Bearer YOUR_API_KEY"

You should see a JSON list of available models. 🎉

Step 4: Chat with a Model

Now let's have a conversation:

curl https://api.tensorx.ai/v1/chat/completions \
  -H "Content-Type: application/json" \
  -H "Authorization: Bearer YOUR_API_KEY" \
  -d '{
    "model": "deepseek/deepseek-chat-v3.1",
    "messages": [
      {"role": "user", "content": "Hello! What can you help me with?"}
    ]
  }'

from openai import OpenAI

client = OpenAI(
    api_key="YOUR_API_KEY",
    base_url="https://api.tensorx.ai/v1"
)

response = client.chat.completions.create(
    model="deepseek/deepseek-chat-v3.1",
    messages=[
        {"role": "user", "content": "Hello! What can you help me with?"}
    ]
)

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

import OpenAI from 'openai';

const client = new OpenAI({
  apiKey: 'YOUR_API_KEY',
  baseURL: 'https://api.tensorx.ai/v1'
});

const response = await client.chat.completions.create({
  model: 'deepseek/deepseek-chat-v3.1',
  messages: [
    { role: 'user', content: 'Hello! What can you help me with?' }
  ]
});

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

Step 5: Check Your Usage

Go to Dashboard → Usage
See your request history with timestamps, models, tokens, and costs
Export to CSV if needed

That's It! ✅

You're now ready to build with TensorX. Here's what to explore next:

Already Using OpenAI?

TensorX is a drop-in replacement. Just change two things:

# Before (OpenAI)
client = OpenAI(api_key="sk-...")

# After (TensorX)
client = OpenAI(
    api_key="YOUR_TENSORX_KEY",
    base_url="https://api.tensorx.ai/v1"
)

That's it! All your existing code works unchanged.
