Install the OpenAI SDK<\/h2>\n<p>For Python, install the official library with <code>pip install openai<\/code>. Then set your key as an environment variable to keep it out of your code:<\/p>\n<p><code>export OPENAI_API_KEY=\"your-key\"<\/code><\/p>\n<h2>2. Make Your First Request<\/h2>\n<p>Here&#8217;s a minimal example using the Responses API:<\/p>\n<pre><code>from openai import OpenAI\nclient = OpenAI()\nresponse = client.responses.create(\n    model=\"gpt-4o-mini\",\n    input=\"Hello\"\n)\nprint(response.output_text)<\/code><\/pre>\n<h2>3. Configure Key Parameters<\/h2>\n<p>A few settings matter for cost and quality:<\/p>\n<ul>\n<li><strong>Model:<\/strong> gpt-4o for complex tasks, gpt-4o-mini for lighter workloads.<\/li>\n<li><strong>Max tokens:<\/strong> limit response length to control spending.<\/li>\n<li><strong>Temperature:<\/strong> lower values give more focused outputs.<\/li>\n<li><strong>System prompt:<\/strong> define the assistant&#8217;s role and tone.<\/li>\n<\/ul>\n<h2>4. Best Practices and Pitfalls<\/h2>\n<ul>\n<li>Never hardcode your API key; use environment variables or a secrets manager.<\/li>\n<li>Add retry logic with exponential backoff to handle rate limits.<\/li>\n<li>Monitor usage in the OpenAI dashboard to avoid surprise charges.<\/li>\n<\/ul>\n<h2>Conclusion<\/h2>\n<p>That&#8217;s the core workflow for using the ChatGPT API. Once it works, explore streaming responses, function calling, and the Assistants API to build more powerful applications.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>How to Use the ChatGPT API: A Step-by-Step Guide for Developers The ChatGPT API lets you integrate OpenAI&#8217;s conversational models into your own applications.
