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

  1. Compose messages and set model parameters.
  2. Define tools or function schemas if your flow needs them.
  3. Copy the generated curl, Python, or JavaScript snippet.
