Overview

LemonData is easiest to integrate through:
  • official OpenAI SDKs for OpenAI-compatible and Responses-style usage
  • official Anthropic SDKs for Claude-native /v1/messages
  • official Gemini / Google AI tooling when you specifically need Gemini-native request shapes

OpenAI Python

pip install openai

OpenAI Node

npm install openai

OpenAI Go

go get github.com/openai/openai-go/v3

Anthropic SDK

Native Claude Messages API support

​
OpenAI SDK Example

Use this as the default starting point for new projects: 
from openai import OpenAI

client = OpenAI(
    api_key="sk-your-api-key",
    base_url="https://api.lemondata.cc/v1"
)

response = client.responses.create(
    model="gpt-5.4",
    input="Explain LemonData in one sentence."
)

print(response.output_text)

​
OpenAI Go Example

package main

import (
    openai "github.com/openai/openai-go/v3"
    "github.com/openai/openai-go/v3/option"
)

func main() {
    client := openai.NewClient(
        option.WithAPIKey("sk-your-api-key"),
        option.WithBaseURL("https://api.lemondata.cc/v1"),
    )

    _ = client
}

​
Anthropic SDK Example

from anthropic import Anthropic

client = Anthropic(
    api_key="sk-your-api-key",
    base_url="https://api.lemondata.cc"
)

message = client.messages.create(
    model="claude-sonnet-4-6",
    max_tokens=1024,
    messages=[{"role": "user", "content": "Hello!"}]
)

​
Best Practices

If your SDK supports both responses and chat.completions, start with responses.
Pass LemonData base URLs directly in your client configuration instead of relying on older environment-variable aliases.
Use the Anthropic SDK for Claude-native features such as extended thinking, and otherwise prefer the OpenAI SDK for broad compatibility.
