Function Calling Definition

About Function Calling Definitions

Build a clean function calling definition for LLM integrations without hand-editing nested JSON. Start from a sample payload or an existing schema, then copy the generated object into your API code or prompt tooling.

Why use a generator?

Function definitions tend to grow repetitive and error-prone once descriptions, required fields, and strict validation rules are involved. A generator helps you shape the initial JSON quickly, then review the contract before production use.

Key Features

• Dual input modes for sample JSON or existing schema documents.
• Automatic function name sanitization to match common API naming rules.
• Strict mode toggle for tighter runtime validation behavior.
• Browser-side generation so sensitive schemas stay local.

How to Use

1. Enter a function name and short operational description.
2. Paste either a sample payload or a JSON Schema and choose the matching mode.
3. Generate the definition, review the result, and paste it into your tool-calling setup.
