Unlike the web interface, the API gives you programmatic control over models, context, and costs. Here&#8217;s how to get started in a few minutes.<\/p>\n<h2>1. Get Your API Key<\/h2>\n<p>Sign up at platform.openai.com, open the API keys page, and create a new secret key. Store it in an environment variable \u2014 never hardcode it in client-side code.<\/p>\n<p><img decoding=\"async\" src=\"https:\/\/sumberlaba.com\/wp-content\/uploads\/2026\/10\/article-1792623658455.jpg\" alt=\"Article illustration\" style=\"display:block;margin:20px auto;max-width:100%;height:auto;border-radius:8px;\" \/><\/p>\n<h2>2. Install the SDK<\/h2>\n<p>OpenAI provides official libraries. With Python:<\/p>\n<ul>\n<li><code>pip install openai<\/code><\/li>\n<li>Set <code>OPENAI_API_KEY<\/code> in your shell<\/li>\n<\/ul>\n<h2>3. Send Your First Request<\/h2>\n<p>The modern endpoint is <code>chat.completions<\/code>. Pass a list of messages with roles: <code>system<\/code> sets behavior, <code>user<\/code> is the prompt, <code>assistant<\/code> is prior replies.<\/p>\n<ul>\n<li>Model: use <code>gpt-4o-mini<\/code> for cheap testing<\/li>\n<li>Messages: keep context short to save tokens<\/li>\n<li>Temperature: 0 for factual, 1 for creative<\/li>\n<\/ul>\n<h2>4. Handle Responses and Errors<\/h2>\n<p>Read <code>response.choices[0].message.content<\/code> for the text. Wrap calls in try\/except and respect rate limits with simple retries and backoff. Log token usage to monitor spend.<\/p>\n<h2>Conclusion<\/h2>\n<p>Start with small prompts, iterate, and add streaming or function calling once the basics work. The same pattern scales to production apps.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>How to Use the ChatGPT API: A Beginner&#8217;s Step-by-Step Tutorial OpenAI&#8217;s ChatGPT API lets you embed conversational AI into your own apps, scripts, and workflows.
