HaiToken LLM gateway is compatible with OpenAI and Anthropic Claude API protocols. You can get started in three steps: get your API key, call the API, and connect to AI tools.

​
Step 1: Get your API key

  1. Register and log in to the HaiToken console
  2. Navigate to Token management in the left sidebar
  3. Click Create API Key, enter a name, and generate your key
  4. Copy and securely store the generated API key (it is shown only once)
Keep your API key secure. Do not expose it in client-side code or public repositories.

​
Step 2: Call the API

HaiToken offers two API formats. Choose the one that matches the model you want to use.

​
OpenAI format

For OpenAI-compatible models, using the POST /v1/chat/completions protocol. 
import requests

url = "https://api.haitoken.ai/v1/chat/completions"
headers = {
    "Authorization": "Bearer YOUR_API_KEY",
    "Content-Type": "application/json"
}
data = {
    "model": "gpt-4o",
    "messages": [
        {"role": "user", "content": "Hello, introduce yourself please"}
    ]
}

response = requests.post(url, json=data, headers=headers)
print(response.json())

​
Claude format

For Anthropic Claude models, using the POST /v1/messages protocol.
When calling the Claude format API, include the anthropic-version header. The recommended value is 2023-06-01.
import requests

url = "https://api.haitoken.ai/v1/messages"
headers = {
    "Authorization": "Bearer YOUR_API_KEY",
    "Content-Type": "application/json",
    "anthropic-version": "2023-06-01"
}
data = {
    "model": "claude-sonnet-4-0",
    "max_tokens": 1024,
    "messages": [
        {"role": "user", "content": "Hello, introduce yourself please"}
    ]
}

response = requests.post(url, json=data, headers=headers)
print(response.json())

​
Step 3: Connect to AI tools

Once you have your API key and the API is verified, you can connect HaiToken to popular AI coding tools.

​
Cursor

  1. Open Cursor, go to Settings > Models
  2. Enter your API key in the OpenAI API Key field
  3. Set OpenAI Base URL to https://api.haitoken.ai/v1
  4. Save and select from the available models in the model list

​
Claude Code

  1. Set environment variables in your terminal:
export ANTHROPIC_API_KEY="YOUR_API_KEY"
export ANTHROPIC_BASE_URL="https://api.haitoken.ai/"
  1. Launch Claude Code to start using it.

​
Open Code

  1. Add haitoken directly from the OpenCode TUI:
Launch the OpenCode TUI Type /connect In the provider list, choose “Other” (custom endpoint) Fill in: Base URL: https://api.haitoken.ai/v1 API Key: your haitoken API key After saving, type /models and switch to the newly added model
  1. Configure provider and base URL in the opencode.json file at your project root:
"provider": {
    "haitoken": {
      "models": {
        "deepseek-v4-flash": {
          "name": "deepseek-v4-flash"
        },
        "deepseek-v4-pro": {
          "name": "deepseek-v4-pro"
        },
      },
      "name": "haitoken",
      "npm": "@ai-sdk/openai-compatible",
      "options": {
        "baseURL": "https://api.haitoken.ai/v1"
      }
    }
  }
