Quick Start

1. Get Your API Key

Log in to the AIone Console and create a new key on the API Keys page.

We recommend creating separate keys for each environment or use case to simplify access control, usage tracking, and troubleshooting.

2. Send Your First Request

AIone is fully compatible with the OpenAI Chat Completions API. Simply set base_url to https://api.portal.aiin1.ai/v1 and use the OpenAI SDK or any compatible client.

Streaming is recommended: For interactive use cases, always enable stream: true. This reduces time-to-first-token from 10+ seconds down to 2-3 seconds, significantly improving the user experience.

from openai import OpenAI
 
client = OpenAI(
    api_key="sk-nex-your-key-here",
    base_url="https://api.portal.aiin1.ai/v1",
)
 
stream = client.chat.completions.create(
    model="claude-sonnet-4-6",
    messages=[
        {"role": "user", "content": "Hello, please introduce yourself"}
    ],
    max_tokens=4096,
    stream=True,
)
 
for chunk in stream:
    content = chunk.choices[0].delta.content
    if content:
        print(content, end="", flush=True)
print()

Python (Non-Streaming)

from openai import OpenAI
 
client = OpenAI(
    api_key="sk-nex-your-key-here",
    base_url="https://api.portal.aiin1.ai/v1",
)
 
response = client.chat.completions.create(
    model="claude-sonnet-4-6",
    messages=[
        {"role": "user", "content": "Hello, please introduce yourself"}
    ],
    max_tokens=4096,
)
 
print(response.choices[0].message.content)
import OpenAI from 'openai';
 
const client = new OpenAI({
  apiKey: 'sk-nex-your-key-here',
  baseURL: 'https://api.portal.aiin1.ai/v1',
});
 
const stream = await client.chat.completions.create({
  model: 'claude-sonnet-4-6',
  messages: [
    { role: 'user', content: 'Hello, please introduce yourself' },
  ],
  max_tokens: 4096,
  stream: true,
});
 
for await (const chunk of stream) {
  const content = chunk.choices[0]?.delta?.content;
  if (content) process.stdout.write(content);
}
console.log();

cURL (Streaming)

curl https://api.portal.aiin1.ai/v1/chat/completions \
  -H "Content-Type: application/json" \
  -H "Authorization: Bearer sk-nex-your-key-here" \
  -d '{
    "model": "claude-sonnet-4-6",
    "messages": [
      {"role": "user", "content": "Hello, please introduce yourself"}
    ],
    "max_tokens": 4096,
    "stream": true
  }'

3. Switch Models

All models are served through the unified v1/chat/completions endpoint. Simply change the model parameter to switch:
