This tutorial covers the essentials: getting an API key, installing the SDK, and running your first request.<\/p>\n<h2>Step 1: Get Your API Key<\/h2>\n<p>Log in to the OpenAI platform, go to the API keys section, and click &#8220;Create new secret key.&#8221; Copy it immediately and store it securely. Never share your key or commit it to GitHub.<\/p>\n<p><img decoding=\"async\" src=\"https:\/\/via.placeholder.com\/800x600\/4a90d9\/ffffff?text=how%20to%20use%20openai%20api\" alt=\"Article illustration\" style=\"display:block;margin:20px auto;max-width:100%;height:auto;border-radius:8px;\" \/><\/p>\n<h2>Step 2: Install the SDK<\/h2>\n<p>For Python, install the official package with pip:<\/p>\n<pre><code>pip install openai<\/code><\/pre>\n<p>Set your API key as an environment variable to keep it out of your code:<\/p>\n<pre><code>export OPENAI_API_KEY=\"your-key-here\"<\/code><\/pre>\n<h2>Step 3: Make Your First Request<\/h2>\n<p>Create a file named <code>test_openai.py<\/code>:<\/p>\n<pre><code>from openai import OpenAI\nclient = OpenAI()\n\nresponse = client.chat.completions.create(\n    model=\"gpt-4o-mini\",\n    messages=[\n        {\"role\": \"system\", \"content\": \"You are a helpful assistant.\"},\n        {\"role\": \"user\", \"content\": \"Say hello in one sentence.\"}\n    ]\n)\nprint(response.choices[0].message.content)<\/code><\/pre>\n<p>The <code>messages<\/code> array controls the conversation. The system message sets the assistant&#8217;s behavior, while the user message provides the instruction.<\/p>\n<h2>Best Practices<\/h2>\n<ul>\n<li>Use environment variables to secure your API key.<\/li>\n<li>Test with <code>gpt-4o-mini<\/code> to keep costs low.<\/li>\n<li>Set <code>max_tokens<\/code> to control response length and cost.<\/li>\n<li>Add error handling to manage rate limits and network issues.<\/li>\n<\/ul>\n<h2>Conclusion<\/h2>\n<p>You can now call OpenAI models from your code.
