Quickstart

Make your first API request in under a minute. Qubax AI is fully OpenAI-compatible — if you've used the OpenAI API before, you already know how to use Qubax.

1. Create an account

2. Add credits

Go to Billing and top up with 200+ coins including BTC, ETH, SOL, USDT & USDC. Minimum $3. Credits never expire.

3. Create an API key

Go to API Keys and click "Create API Key". Your key starts with qbx_live_. Copy it — you won't see it again.

4. Make your first request

Using the OpenAI Python SDK:

Python

from openai import OpenAI

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

response = client.chat.completions.create(
    model="claude-opus-4.8",
    messages=[
        {"role": "user", "content": "Hello! What can you do?"}
    ]
)

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

Or with cURL:

Shell

curl https://api.qubax.ai/v1/chat/completions \
  -H "Authorization: Bearer qbx_live_..." \
  -H "Content-Type: application/json" \
  -d '{
    "model": "claude-opus-4.8",
    "messages": [
      {"role": "user", "content": "Hello!"}
    ]
  }'

That's it. You just made your first AI request through Qubax at up to 99% off OpenRouter pricing.
