Function Calling & Tool Execution
Connect models to external APIs, databases, and custom functions using OpenAI-compatible tool specifications.
API100 supports standard tool calling across Claude 3.5 Sonnet, GPT-4o, and Gemini 1.5 Pro.
Pass a list of tools with JSON schemas into the tools parameter. When the model determines an external function is needed, it returns a tool_calls payload containing function names and parsed arguments.
