Get started

GreenPT exposes an OpenAI-compatible API at https://api.greenpt.ai/v1, so there is no GreenPT-specific SDK to install. Follow the steps below to go from signup to your first response in a few minutes.

1. Create an account

Sign up for GreenPT and pick any subscription — API-only, Starter, Pro, Teams, or Enterprise — to unlock API access.

Sign up at account.greenpt.ai →

2. Get an API key

Once your subscription is active, generate an API key from the dashboard.

Manage API keys →

3. Install an OpenAI-compatible client

Use the official OpenAI client for your language and override the base URL.

npm install openai

pip install openai

4. Configure the client

Point the SDK at https://api.greenpt.ai/v1 and pass your API key. Store the key in an environment variable rather than hard-coding it.

export GREENPT_API_KEY=sk-your_api_key

import OpenAI from 'openai';

const client = new OpenAI({
  apiKey: process.env.GREENPT_API_KEY,
  baseURL: 'https://api.greenpt.ai/v1',
});

from openai import OpenAI

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

5. Make your first API call

Test your integration with a simple chat-completion request.

curl https://api.greenpt.ai/v1/chat/completions \
  -H "Content-Type: application/json" \
  -H "Authorization: Bearer $GREENPT_API_KEY" \
  -d '{
    "model": "gemma4",
    "messages": [
      { "role": "user", "content": "Hello, how are you?" }
    ],
    "stream": false
  }'

6. Verify the connection

List available models to confirm your client is configured correctly.

curl https://api.greenpt.ai/v1/models \
  -H "Authorization: Bearer $GREENPT_API_KEY"
