}About the Openai Request Builder
Chat API calls have a dozen parameters that interact — temperature, max tokens, function definitions, message ordering. Getting the JSON right is half the friction of prototyping.
This builder composes the request visually: model, system and user messages, tools, and sampling parameters — then emits ready-to-run curl, Python, and JavaScript. Your API key is never needed here; you generate the call, you run it from your own terminal.
How to use
- Compose messages and set model parameters.
- Define tools or function schemas if your flow needs them.
- Copy the generated curl, Python, or JavaScript snippet.
