Native Claude API Usage Guide

Claude Models Can Be Accessed via the Official Native Interface

• This method is specific to Claude models. For non-Claude models, please use the OpenAI API format.

API Request Examples

1. Using curl for API Requests:

curl https://aihubmix.com/v1/messages \ # Replace the official endpoint with AiHubMix’s API endpoint
     --header "x-api-key: $ANTHROPIC_API_KEY" \ # Replace this with the API key you generated on AiHubMix
     --header "anthropic-version: 2023-06-01" \
     --header "content-type: application/json" \
     --data \
'{
    "model": "claude-3-5-sonnet-20241022",
    "max_tokens": 1024,
    "messages": [
        {"role": "user", "content": "Hello, world"}
    ]
}'

2. Using the Python Library:

import anthropic

# Initialize the Anthropics client
client = anthropic.Anthropic(
    # Replace this with the API key you generated on AiHubMix
    api_key="ANTHROPIC_API_KEY",
    base_url="https://aihubmix.com"
)

# Construct your message
message = client.messages.create(
    model="claude-3-7-sonnet-20250219",
    max_tokens=1024,
    messages=[
        {"role": "user", "content": "Hello, Claude"}
    ]
)

# Print the response content
print(message.content)

Using Claude in Applications (Example: Lobe-Chat)

Here’s how you can configure Claude models in a third-party application like Lobe-Chat:

1. Navigate to the settings page and select Claude as your model provider.
2. Enter your API Key from AiHubMix.
3. Set the API proxy endpoint to:

   https://aihubmix.com
4. (Recommended) Enable the "Client Request Mode" option.
5. Add your chosen model to the model list.
   • It’s recommended to copy the model name from AiHubMix's settings page and paste it in the application.
